For the first time on the basis of luminescence spectroscopy the influence of low temperature elastic uniaxial stress on the process of exciton-phonon interaction in crystal KI was studied by registering temperature quenching of self-trapped exciton

The X-ray luminescence spectra at low temperature (90K) uniaxial deformation were researched for KI and KI-Na crystals, that were stored for more than 10 years. The following regularities were observed: firstly, the intensities of the intrinsic emiss

Using X-ray luminescence spectra, the enhancement of both σ-luminescence of self-trapped excitons and Ех luminescence (band maxima at 3.89 and 3.1 eV, respectively) has been revealed for the first time in RbI single crystals exposed to elastic uni

The efficiency of radiation defects formation in alkali halide crystals (AHC) was studied by the method of absorption spectroscopy. However, it is not possible to study the deformation-stimulated processes in detail by the absorption spectrum of radi

The effect of uniaxial stress applied at 80 K along the 〈1 1 0〉 crystal axis on the self-trapped exciton (STE) and impurity-induced luminescence has been studied for NaCl and NaBr crystals under X-ray and VUV-light excitation. It has been shown t

By using luminescence spectroscopy, we have established the influence of low-temperature uniaxial deformation on the configuration of a self-trapped exciton (STE) in alkali halide crystals (AHC) at the instant of radiative relaxation. In face-centere
