FIELD: chemical industry.
SUBSTANCE: invention relates to a method for producing borate phosphors by heat treatment, and a mixture of lanthanum oleate, europium oleate, bismuth extract with boric acid with the introduction of octanol and trioctylamine is used as a precursor, which is heated first for 1 hour at 200°C and then at a temperature of 550-750°C for 2 hours.
EFFECT: new solution for obtaining borate phosphors by heat treatment.
