Abstract 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-As 2 S 3 , a-As 2 Se 3 and a-Se. 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-As 2 S 3, a-As 2 Se 3 and a -Se. Results agree quite well with the experimental results. Results agree quite well with the experimental results. The theory is quite general and can be applied to any amorphous materials, including organics. The theory is quite general and can be applied to any amorphous materials, including organics.
