摘要:
There is provided a phosphor down converting element based on fluoropolymer resin and a method for fabricating the same. There is further provided a method for using said phosphor down converting element to generate white light from a radiation source. The method for fabricating phosphor down converting element includes preparing an appropriate phosphor powder mixture that is capable of absorbing a first band of wavelengths and emitting a second band of wavelengths being greater in length than the first bands, incorporating the phosphor powder mixture into or on a phosphor carrier element comprising a fluoropolymer material, and molding the phosphor down converting elements into useful shapes. Fluoropolymers are the most chemically inert of all plastics, can withstand both extremely high and low temperatures, and show a resistance to weavering and UV degradation, making fluoropolymers optimal for use as a phosphor carrier.
