LED and phosphor for short-wave semiconductor

摘要

A phosphor for short-wave semiconductor LEDs to create white radiation that comes from the lumen of the phosphor and the blue radiation of the heterojunction absorbed by the phosphor. The phosphor is prepared from a YAG-based substrate and added with N-3 and F-1, having the chemical formula of (SigmaLn)3Al5O12-deltaN-3delta/2F-1delta/2, in which SigmaLn=Y1-x-y-zGdxLuyCez. The phosphor has high lumen brightness and the characteristics of high stability of light chromaticity and high durability.
