Abstract
High potential of two-photon confocal microscopy for photoluminescent tomography of bulk semiconductor crystals are demonstrated in this work using ZnSe crystals as an example. The first results of investigation of ZnSe bulk crystals, both undoped and doped by 3d metals, are presented. Appearance of luminescence quenching centres in specific parts of crystals and grain recombination activity are demonstrated by the proposed method; these phenomena cannot be detected by other luminescence-based methods.
