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 RMO.sub.3, 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 R.sub.2CuO.sub.4, 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
RZ.sub.2Cu.sub.3O.sub.6, wherein R is at least one rare-earth element,
and Z is at least one alkali-earth metal.
