Examples of the present invention relate to a phosphor plate composition having a wide emission region while improving luminance. The composition comprises: yttrium aluminum garnet (YAG) or gadolinium yttrium aluminum garnet ((Gd, Y) AG) phosphor powders doped with any one dopant selected from cerium (Ce), gadolinium (Gd) and neodymium (Nd); and a sintering agent of any one selected from lithium fluoride (LiF), magnesium oxide (MgO) and spinel (MgAl2O4).
Selon des exemples, la présente invention se rapporte à une composition de plaque de luminophore ayant une zone d'émission étendue tout en améliorant la luminance. La composition comprend : des poudres de luminophores de grenat d'yttrium-aluminium (YAG) ou de grenat de gadolinium-yttrium-aluminium ((Gd, Y) AG) dopées avec un dopant quelconque choisi parmi le cérium (Ce), le gadolinium (Gd) et le néodyme (Nd); un agent de frittage choisi parmi l'un quelconque du fluorure de lithium (LiF), de l'oxyde de magnésium (MgO) et d'une spinelle (MgAl2O4).
본 발명의 실시예들은 휘도를 향상시키면서도 넓은 발광영역을 가지는 형광체 플레이트 조성물에 대한 발명으로, 세륨(Ce), 가돌리늄(Gd) 및 네오디뮴(Nd) 중에서 선택된 어느 하나의 도펀트가 도핑된 이트륨알루미늄가넷(YAG) 또는 가돌리늄이트륨알루미늄가넷((Gd,Y)AG) 형광체 분말; 및 리튬플로라이드(LiF), 산화마그네슘(MgO) 및 스피넬(MgAl2O4) 중에서 선택된 어느 하나의 소결제를 포함한다.
