FIELD: physics.
SUBSTANCE: inorganic composition for producing electroluminescent material contains the following, pts.wt: 80-95 semiconductor compound consisting of group II and group VI elements; 0.001-3 iridium source or a combination of an iridium source and at least one source of metal other than iridium; 3-9 activator. To obtain electroluminescent material, the inorganic composition is subjected to an explosion using a propellant and/or blasting explosive in a sealed vessel followed by thermal treatment. The obtained electroluminescent material is used as a light-emitting layer between electrodes of an inorganic electroluminescent device whose brightness when excited with direct current is equal to or higher than 10000 cd/m2.
EFFECT: invention not only increases brightness but also prolongs the service life of the light-emitter.
