FIELD: chemistry. ^ SUBSTANCE: present invention can be used in laser technology as anti-reflection filters - saturable absorbers for lasers, working in the near infrared range of the spectrum. Formation of nanoparticles in the glass, with size ranging from 1.2 to 10 nm and size distribution closer to monodisperse distribution, is achieved as a result of secondary thermal treatment of the glass, at temperature close to glass transition temperature. The proposed glass consists of the following components with the given ratios, in wt %: P2O5 45-55, Ga2O3 14-30, Na2O 15.5-16.5 ZnO 3.5-6.1, NaF 1.3-2, AlF3 1-2.6, PbF2 0.3-2.0, PbSe 2.4-2.8. ^ EFFECT: formation of nanoparticles of lead selenide with small dimensions, characterised by high concentration and narrow size distribution, providing for spectral absorption and anti-reflection in the near infrared range of the spectrum. ^ 2 tbl |
