Abstract

In this work, present the the experimental and theoretical results of a study of ZnSe 2 O 5 nanocrystals, which
were synthesized by electrochemical deposition using a sulfate solution at a voltage of 1.25 V into an ion track template. The morphology and transverse cleavage of the studied samples using scanning electron microscopy was studied. An X-ray diffraction study showed the creation of ZnSe 2 O 5 nanocrystals with an orthorhombic crystal structure. Non-empirical calculations showed that ZnSe 2 O 5 has a direct band gap at the Г-point, and the calculated effective atomic charges indicate a significant covalent contribution to chemical bonds, forming the mixed ion-covalent bond. Photoluminescence was excited by light with a wavelength of 300 nm and, in our opinion, is a symbiosis of the luminescence of zinc oxide and zinc selenide.
