FIELD: nanotechnologies.
SUBSTANCE: invention may be used for production of photo elements of solar batteries, for making solar batteries photo elements, for making optical devices, ionising-radiation detectors and catalysts. Method of obtaining nanoparticles of cadmium telluride with wurtzite structure includes decomposition of cadmium telluride crystals in melt of potassium hydroxide or natrium in nitrogen atmosphere till complete homogenisation of obtained product. Melt is cooled to (-15)-(-20) °C and water-spirit-ammoniac mixture is added gradually during mixing and cooling with temperature (-15)-(-20) °C till obtaining of final solution with temperature not exceeding -5°C. Precipitated cadmium telluride is filtered.
EFFECT: invention allows to obtain nanoparticles of cadmium telluride with wurtzite structure and size about 1 nm and to simplify procedure of its obtainment.
