FIELD: fiber-optic technology.
SUBSTANCE: invention relates to the production of gallium (II) sulfide, which is a promising material for semiconductor optoelectronic technology and infrared optics. The method for obtaining gallium (II) sulfide includes two-temperature chemical synthesis in a closed volume from elementary gallium and sulfur taken in a stoichiometric ratio. The gallium melt has a temperature of 1050-1100°C, and the sulfur melt is 300-350°C. The synthesis is carried out in a vacuum in the presence of ultraviolet radiation.
EFFECT: invention makes it possible to obtain a single-phase GaS product without the use of explosive hydrogen.
