Dispersion characteristic of photoluminescence decay times of phosphor YAG: Ce, Gd

Abstract

The dispersion of the characteristic decay times of gadolinium co-doped yttrium aluminum garnet doped with cerium phosphors were studied. In the present work, an ultraviolet semiconductor laser ([lambda][em]=375 nm, [tau]=1 ns) was used as excitation source for measuring kinetics characteristics of phosphor groups based on YAG with different content of cerium.
