摘要：

The radiative lifetime of triplet excitons, is studied here for the first time theoretically in chalcogenide glasses. A new time-dependent exciton-spin-orbit-photon interaction operator is derived and rates of radiative recombination of triplet excitons and corresponding radiative lifetimes are calculated in three chalcogenide glasses, a-As2S3, a-As2Se3 and a-Se. Results agree quite well with the experimental results. The theory is quite general and can be applied to any amorphous materials, including organics.
