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 .
