FIELD: luminescent materials.
SUBSTANCE: invention provides novel electroluminescent material comprised of injecting layer, metal chelate complex-based active luminescent layer, hole-transition layer and hole-injecting layer. Luminescent substance is selected from oxyquinolate metallocomplexes of zinc 8-hydroxy-2-methoxyquinolate and zinc 8-hydroxy-2-methylquinolate. Electroluminescent material shows emission in green spectrum region.
EFFECT: increased heat resistance and widened choice of stable green-emitting materials.
