The complicated spectrum of radiative transitions in sillenite-type crystals is investigated. It is shown that the luminescence excitation spectra (LES) of crystals studied can be divided into three groups: a) the excitation in the fundamental absorp

Two-photon interband absorption spectra are obtained first in PbMoO4 crystals. They are shown to be attributed to indirect two-photon absorption (TPA) with the assistance of phonons to exciton state formed band transitions with the extrema in differe

Les spectres de photoluminescence et d'excitation de la luminescence dependent de la composition du cristal et de la temperature; la variation thermique de l'intensite d'emission et la relaxation de photoluminescence sont etudiees pour tous les crist
