| 简介 |
The composite of the invention comprises (a) a polymer selected from ethylene/vinyl acetate, polyethylene terephthalate, ethylene tetrafluoroethylene, ethylene trifluorochloroethylene, perfluorinated ethylene-propylene, polyvinyl butyral, polyurethane and silicones; (b) an inorganic phosphor based on at least one element selected from rare earth elements, zinc and manganese, which has an external quantum efficiency of greater than or equal to 40% for at least one excitation wavelength of between 350 nm and 440 nm; an absorption of less than or equal to 10% for a wavelength of greater than 440 nm; a mean particle size of less than 1 μm; and this phosphor has an emission maximum in a range of wavelengths between 440 nm and 900 nm. |
