A step forward towards smart white lighting: Combination of glass phosphor and blue LEDs

摘要

We report a broad and intense yellow emission band from Ce~(3+)-doped Low Silica Calcium Aluminosilicate (LSCAS) glass obtained under blue light excitation. The C1E 1931 x-y chromatic diagram shows that the association of the Ce~(3+):LSCAS glass with 405 nm blue LED presents emission very close to the ideal white light position.
