В статье представлены исследования нанопроволок селенида меди, впервые полученных в результате темплэйтного синтеза. Данный метод позволяет точно контролировать размеры и морфологию наноструктур, что свидетельствует о его высокой эффективности в получении однородных и хорошо осажденных нанопроволок селенида меди. Трековый темплэйт SiO2/Si получен облучением на ускорителе ДЦ-60 (Астана, Казахстан), после чего трековый темплэйт подвергается химическому травлению с образованием цилиндрических пор. После облучения и дальнейшего химического травления в трековый темплэйт SiO2/Si осаждали селенид меди методом электрохимического осаждения. Наблюдение за морфологией и количеством осажденных нанопреципитатов проводилось с помощью электронного микроскопа QUANTA 200i с 3D-сканированием. Рентгеновский дифрактометр использовался для определения кристаллографической структуры нанопреципитатов на основе селенида меди. Рентгеноструктурный анализ (РСА) проводился на рентгеновском дифрактометре Rigaku miniflex 600. В результате рентгеноструктурного анализа было обнаружено образование кубической кристаллической фазы нанопроволок селенида меди, электрохимически осажденных на трековом тэмплэйте SiO2/Si. Спектры фотолюминесценции (ФЛ) измеряли на спектрофлуориметре СМ2203 для изучения оптических свойств нанопроволок. Спектры ФЛ регистрировались при комнатной температуре от 300 нм до 800 нм с шагом 5 нм при ксеноновой лампе. Дифференциальное разложение спектров ФЛ показал две основные пики (2,5 и 2,8 эВ).

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).
