FIELD: chemistry.
SUBSTANCE: invention describes a method of modifying anti-Stokes luminophors based on oxychlorides of rare-earth elements, involving treatment of a luminophor with low-melting glass with flow temperature of 560-600°C in amount of 7-20% of the weight of the initial luminophor at 560-600°C for 0.5-1 hour.
EFFECT: obtaining modified anti-Stokes luminophor with high output and high moisture resistance with retention of high level of luminous intensity during infrared excitation.
