摘要：

We report luminescence spectra with spatial and spectral resolution which show the predominant effect of lithium on optical and electrical properties of annealed ZnTe. Lithium is identified in photoluminescence spectra at 5 K whereas SEM visualizes the diffusion of this impurity. We can also observe the effect of high impurity concentration of luminescence with the apparition of excitons bound to LiLi pairs. © 1979.
