Multivariate metal-organic framework compositions and methods of producing multivariate metal-organic frameworks. The metal-organic framework including at least one light-emitting linker in an amount sufficient for the composition to produce broadband emission spectra in high efficiencies.

A digitizer system includes a substrate with indicia having photoluminescent features that uniquely define local areas of the substrate. A sensor device, such as a stylus, may sense radiation emitted from the features, and a controller may determine therefrom the location of the stylus relative to the substrate.

Disclosed is a light-emitting device which comprises: a light-emitting element for emitting a first light in a blue wavelength band; a first wavelength converter for converting the first light into a second light; a second wavelength converter for converting the first light into a third light; and a third wavelength converter for converting the first light into a fourth light, wherein the first to fourth lights have central wavelengths which satisfy the following relationship: [Expression 1] λ1<λ2<λ3<λ4 (wherein λ1 is the central wavelength of the first light; λ2 is the central wavelength of the second light; λ3 is the central wavelength of the third light; and λ4 is the central wavelength of the fourth light.).

The detailed characteristics of the red fluorescence of the human lens—that occurs at the seventh decade of life—is recognized as an example of evolutionary photobiomodulation for repair of the retina, and then used as a paradigm for extending current parametric values for reproducible photobiomodulation. The new photobiomodulation parameters involve relative intensities for wavelength bands within the range of 600 nm to 900 nm.

A composition of matter including a fluorescent assembly and a drilling fluid is provided. The fluorescent assembly includes a matrix material and a plurality of fluorophores held within the matrix material and has an average particle size of at least one millimeter. A method includes introducing the fluorescent assembly into a drilling fluid and circulating the drilling fluid through a well during a drilling operation that creates formation cuttings such that the fluorescent assembly interacts with the formation cuttings, creating tagged cuttings. The method further includes collecting returned cuttings from the circulating drilling fluid at a surface of the well, detecting the presence of the fluorescent assembly on the returned cuttings to identify the tagged cuttings, and correlating the tagged cuttings with a drill depth in the well at a time during the drilling operation.

A pop gear or gang troll includes a wire leader and a plurality of spinner blades. The spinner blades may include a polycarbonate body or a body of some other material, a fragmented reflective material disposed on the polycarbonate body so as to reflect incident light in varying directions depending on the relative location of the incident light, and a luminescent material. The spinner blades may have a shape such as generally fish shaped, ovoid, round, or spoon shaped. A lure includes a polycarbonate body (or a body formed from some other material), a fragmented reflective material disposed on the polycarbonate body so as to reflect incident light in varying directions depending on the relative location of the incident light, a luminescent material, and a hook attached to the body. The body of the lure may have a shape designed to lure fish and/or to cause a desired motion to the lure (e.g., vibration).

The present invention provides a gadolinium oxysulfide sintered body having a high light output. The problem is resolved by a gadolinium oxysulfide sintered body in which the ratio of the light transmittance T.sub.410 of 410 nm to the light transmittance T.sub.512 of 512 nm (T.sub.410/T.sub.512) is from 0.31 to 0.61, or a gadolinium oxysulfide sintered body in which the ratio of the diffraction peak intensity I.sub.y of a phase different from gadolinium oxysulfide appearing at 2θ=from 20 to 29° to the diffraction peak intensity (I.sub.x) of (102) or (011) of gadolinium oxysulfide appearing at 2θ=30°±1° (I.sub.y/I.sub.x) is 0.1 or less in an XRD diffraction pattern and which contains one or more activators selected from the group consisting of praseodymium, terbium, and cerium.
