COLOR-MODIFIED LUMINESCENT CONCENTRATOR
A laminated glass luminescent concentrator is provided which includes a solid medium having a plurality of fluorophores disposed therein. In some embodiments, the fluorophore is a low-toxicity quantum dot. In some embodiments, the fluorophore has significantly reduced self-absorption, which allows for unperturbed waveguiding of the photoluminescence over a long distance. Also disclosed are apparatuses for generating electricity from the laminated glass luminescent concentrator, and its combination with buildings and vehicles.
WARM-COLOR COMPLEX PHOSPHOR, WAVELENGTH CONVERTER AND LIGHT EMITTING DEVICE
Awarm-color complex phosphor includes: a Ce.sup.3+-activated orange phosphor that has an excitation peak within a blue wavelength range of 440 nm or more and less than 480 nm and has a fluorescence peak within an orange wavelength range of 580 nm or more and less than 610 nm; and a Ce.sup.3+-activated red phosphor that has an excitation peak within a green wavelength range of 500 nm or more and less than 550 nm and has a fluorescence peak within a red wavelength range of 610 nm or more and less than 660 nm. Preferably, the Ce.sup.3+-activated red phosphor is a nitride-based compound.
Systems and methods for producing objects incorporating selectably active electromagnetic energy filtering layers and coatings
A system and method are provided for forming body structures including energy filters/shutter components, including energy/light directing/scattering layers that are actively electrically switchable. The filters or components are operable between at least a first mode in which the layers, and thus the presentation of the shutter components, appear substantially transparent when viewed from an energy/light incident side, and a second mode in which the layers, and thus the presentation of the energy filters or shutter components, appear opaque to the incident energy impinging on the energy incident side. The differing modes are selectable by electrically energizing, differentially energizing and/or de-energizing electric fields in a vicinity of the energy scattering layers, including electric fields generated between a pair of transparent electrodes sandwiching an energy scattering layer. Refractive indices of transparent particles, and the transparent matrices in which the particles are fixed, are tunable according to the applied electric fields.
Iridescent Article
A method of decorating an article having an iridescent visual effect and an article with surface decoration are provided. The method comprises depositing a plurality of mono-dispersed particles onto a curved surface of the article, each particle having a size of from about 230 nm to about 360 nm with a polydispersity index (PDI) of below 0.2, to form a layer of regularly-ordered colloidal crystals on a surface having a curvature of at least 0.02 cm.sup.−1. The colloidal crystals create an iridescent visual effect on the surface where multiple colors can be seen as a person views the substrate from different angles, and the intensity and brightness of the colors is at an optimal level.
Infrared ray shielding film
An infrared ray shielding film having a metal particle-containing layer in which hexagonal to circular tabular metal particles are contained in 60% by number or more relative to total number of the metal particles contained in the metal particle-containing layer exhibits excellent infrared ray reflection at a wide range of from 800 nm to 2000 nm and shows little heat ray absorption.
LED lighting units, materials, and optical components for white light illumination
Materials and optical components formed thereof that are suitable for use in lighting units to obtain or approximate white light illumination, including lighting units that utilize one or more light-emitting diodes (LEDs) as a light source.
Optical lens and optical lens module
An optical lens includes a plastic lens body and a plurality of light-absorbing particles. The light-absorbing particles are dispersed in the plastic lens body, are present in an amount ranging from 0.01 wt % to 0.05 wt % based on the total weight of the optical lens, and are capable of absorbing infrared having a wavelength greater than 1100 nm.
Electromagnetic energy-absorbing optical product and method for making
An electromagnetic energy-absorbing optical product useful particularly for automotive and architectural window films is disclosed. The electromagnetic energy-absorbing optical product includes a polymeric substrate and a composite coating with the composite coating including first and second layers each containing a binding group component which together form a complimentary binding group pair.
Optical film, light-emitting device and display device
An optical film, a light-emitting device and a display device are provided. The optical film includes a quantum rod film layer and a light transmission prism layer located on a light emergent side of the quantum rod film layer. The prism layer is configured at the light emergent side of the quantum rod film layer to converge the linearly polarized light transmitted by the quantum rod film layer, so that the brightness of the light located at the light emergent side of the whole optical film is increased.
COLOR FILTER FILM MANUFACTURING METHOD AND COLOR FILTER FILM
The present invention provides a color filter film manufacturing method and a color filer film. The color filter film manufacturing method of the present invention includes forming transparent photoresist layers in blue sub-pixel zones and forming first and second recesses respectively in red and green sub-pixel zones and subjecting bottoms thereof to a treatment for hydrophilicity/hydrophobicity. The difference of hydrophilicity/hydrophobicity between the bottoms of the first and second recesses and a surface of the photoresist layer, in combination with altitude differences, makes the red and green quantum dot materials to respectively form red and green quantum dot layers in the first and second recesses through autonomous flowing. The red and green quantum dot layers are excited by blue backlight source to respectively emit red light and green light, while the blue backlight source directly transmits through the transparent photoresist layers to give off blue light thereby providing three primary colors of red, green, and blue to achieve color displaying, increasing utilization of quantum dots, the effect of autonomous flowing of the quantum dot paste being made better for higher resolution and denser arrangement of pixels, and thus, making it better suitable for manufacture of high-resolution panels than ink-jet printing techniques.
