Calcium reacting photoproteins are a class of self-illuminating proteins that emit light upon contact with calcium. Fluorescent Proteins are small proteins that change the color of light when excited. Fluorescent Proteins and Calcium Activated Photoproteins can be used to enhance, dazzle, amaze, startle, and otherwise entertain an audience by their direct application on to the audience, surroundings, the actors, or sprayed on settings as in the newer 4D movies. The disclosure comprises novel Coelenterazine compounds and methods of use, including a simple delivery device for the photoprotein to create unique and novel cinematic, theatrical, stage, movie and musical concert optical effects by their luminous reaction upon contact with surfaces that contain calcium. Calcium is ubiquitous in and on most surfaces and in the environment; it is this unique property of calcium that makes this a novel use of the photoproteins for entertainment. A generic formula of Coelenterazine as shown. ##STR00001##

A method of treating a reaction mixture comprising light-emitting nanoparticles formed upon reaction of a silica-forming compound in the presence of a light-emitting material in a protic, water-miscible solvent. The method comprises forming a phase-separated system comprising: an aqueous phase comprising the protic, water miscible solvent, an organic phase comprising an organic solvent and a separating solvent; and separating the organic phase. The separating solvent is immiscible with water, miscible with the water-miscible protic solvent and miscible with the organic solvent.

Compositions and methods for optically-verified, sequence-controlled polymer synthesis are described.

The present invention provides a composition containing an inorganic nano-particle structure absorbing blue light and then emitting light and a siloxane compound; a light-conversion thin-film made of the composition; and a display panel using the film. When using the composition, the light-conversion thin-film as an optical member may have high stability. Further, when using the film, a display panel with excellent stability even under high-temperature and high-water conditions may be realized.

The present invention discloses a method of preparing polymeric photoluminescent dots in water using inexpensive non-conjugated polymers. The resulting polymeric photoluminescent dots display the following properties: excellent water dispersibility, low toxicity, high absorptivity, good photo-stability and high quantum yield. The photoluminescent properties are not influenced by aggregation-caused quenching effect. The method is amenable to scale-up and is environmentally friendly.

Described herein is a cost-effective and time-efficient method for producing photochromic contact lenses, in particular, preferably photochromic silicone hydrogel contact lenses, from a polymerizable composition comprising an unique selection and combination of main polymerizable components, a photochromic compound and a visible-light photoinitiator, based on the Lightstream Technology?.
