Abstract

A method for diagnostics of powdered substances is presented using the example of nanopowders of zinc selenide and zinc oxide. The method is based on the fiber-optic recording of photoluminescence spectra under laser ultraviolet (266 nm) excitation. The developed method can be used to control the quality of a large class of dielectric and semiconductor structures luminescing under the action of ultraviolet radiation
