    • 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.
    • 本发明提供了以很少的能量消耗发射非常明亮的光,电能转换成热量损失小的电致发光材料,并且由于长期使用而受到很少劣化,特别是发出蓝色至绿色的无机电致发光材料 波长短于黄色的光。 具体地,本发明涉及以下三种类型的电致发光材料:(1)一种电致发光材料,其包括具有由通式RMO3表示的钙钛矿型晶体结构的氧化物,其中R是至少一种稀土元素,M 是选自Al,Mn和Cr中的至少一种; (2)一种电致发光材料,其包含具有由通式R2CuO4表示的钙钛矿型晶体结构的氧化物,其中R是至少一种稀土元素; 和(3)包含具有由通式RZ2Cu3O6表示的钙钛矿型晶体结构的氧化物的电致发光材料,其中R是至少一种稀土元素,Z是至少一种碱土金属。
