摘要:
The present invention provides electroluminescent materials that emit very bright light with little energy consumption, little loss of energy converted into heat, etc., and suffers from little deterioration due to long-term use, in particular, inorganic electroluminescent materials that emit blue to green light having a wavelength shorter than yellow. Specifically, the present invention relates to the following three types of electroluminescent material: (1) An electroluminescent material including an oxide having a perovskite-type crystal structure represented by General Formula RMO3, wherein R is at least one rare-earth element, and M is at least one member selected from the group consisting of Al, Mn, and Cr; (2) an electroluminescent material including an oxide having a perovskite-type crystal structure represented by General Formula R2CuO4, wherein R is at least one rare-earth element; and (3) an electroluminescent material including an oxide having a perovskite-type crystal structure represented by General Formula RZ2Cu3O6, wherein R is at least one rare-earth element, and Z is at least one alkali-earth metal.
