Abstract

Two kinds of intrinsic luminescence in mixed AgBr_1-xCl_x (1 ≤ × < 0) crystals as well as optical fibers have been observed and studied. The first kind of luminescence arises due to localized exciton states and is controlled by a diffusion of intrinsic lattice defects, which are assumed to be interstitial silver atoms, Ag_i^o. Dependence of the parameters of this process on crystal composition has been investigated in terms of spatially well correlated Frenkel defect recombinations. The main effect found was the linear increase of the Ag_i^o migration energy with the crystal composition x. The second kind of luminescence arising due to exciton molecules has been shown to be sensitive to the solid solution composition and the quality of a crystal. It is shown that this luminescence correlates with the optical losses of the fibers studied.
