摘要：

The first measurements of total light decay of photoluminescence (PL) of a chalcogenide glass in the time regime >100 ns are reported. The time decay is described by t-m exp(- nu 2t) where m=1- delta +T/T 0, at temperature T with nu 2-1=1.4 ms, delta =0.1, T0=300K. These results allow a microscopic description of PL in a-As2S3 and indicate that PL may arise from charge-transfer de-excitation of defect pairs.
