Abstract

This paper presents a study of copper selenide nanowires obtained for the first time by template synthesis. This method allows precise control of the size and morphology of nanostructures, which indicates its high efficiency in obtaining homogeneous and well-deposited copper selenide nanowires. The SiO2/Si track template was obtained by irradiation on a DC-60 accelerator (Astana, Kazakhstan), after which the track template was chemically etched to form cylindrical pores. After irradiation and further chemical etching, copper selenide was deposited into the SiO2/Si track template by electrochemical deposition method. The morphology and amount of deposited nanoprecipitates were observed using a QUANTA 200i electron microscope with 3D scanning. X-ray diffractometer was used to determine the crystallographic structure of copper selenide nanoprecipitates. X-ray diffraction analysis (XRD) was carried out on a Rigaku miniflex 600 X-ray diffractometer. The XRD analysis revealed the formation of cubic crystalline phase of copper selenide nanowires electrochemically deposited on SiO2/Si track template. Photoluminescence (PL) spectra were measured on a CM2203 spectrofluorimeter to study the optical properties of the nanowires. The PL spectra were recorded at room temperature from 300 nm to 800 nm in 5 nm steps under a xenon lamp. Differential decomposition of the FL spectra showed two main peaks (2.5 and 2.8 eV).
