文摘

We have studied the luminescent properties of three CdS-based solid-solution series, resulting from isovalent anion substitution (CdS_1−x Te_x), isovalent cation and anion substitutions (Cd_1−x Zn_xS_1−x Te_x), and heterovalent cation substitution in combination with isovalent anion substitution (Cd_1−x In_2x/3S_1−x Te_x). The last two systems have been studied for the first time. The results demonstrate that red or near-IR lumiescence occurs in the three systems, but CdS crystals codoped with In and Te are more attractive because of the high impurity-related emission intensity at rather low In and Te concentrations.
