The present invention relates to a metal fluoride red phosphor and an application of the phosphor as a light emitting element, the metal fluoride red phosphor having a tetragonal crystal structure of a novel composition, and emitting light in the red color wavelength by being excited by ultraviolet rays or a blue excitation source, thereby being usefully applicable to a light emitting element such as a light emitting diode, a laser diode, a surface emitting laser diode, an inorganic electroluminescence element, and an organic electroluminescence element. La présente invention concerne un phosphore rouge fluorure métallique et une application du phosphore comme élément électroluminescent, le phosphore rouge fluorure métallique ayant une structure cristalline tétragonale d'une composition nouvelle, et émettant de la lumière dans la longueur d'onde de couleur rouge en étant excité par les rayons ultraviolets ou une source d'excitation bleue, étant ainsi utilement applicable à un élément électroluminescent tel qu'une diode électroluminescente, une diode laser, une diode laser à émission en surface, un élément électroluminescent inorganique, et un élément électroluminescent organique. 본 발명은 자외선 또는 청색의 여기원에 의해 여기되어 적색계 파장을 발광하므로 발광다이오드, 레이저다이오드, 면발광 레이저다이오드, 무기 일렉트로루미네센스 소자, 유기 일렉트로루미네센스 소자와 같은 발광소자에 유용하게 적용되는, 신규 조성의 정방정계(tetragonal) 결정구조를 가지는 금속불화물 적색 형광체 및 이 형광체를 발광소자로 응용하는 것에 관한 것이다.
