The conditions of the formation of external protective SiO2 layer with a controlled thicknes of 5-50 nm were established. Studied were the structural, optical and luminescent characteristics of the obtained material by the methods of electron microscopy, Product Description popup.authors Єрмолаєва Юлія Володимировна Коршикова Тетяна Іванівна Матвєєвська Н.А.
