발광 조성물은 화학식 REME를 특징으로 하며, 상기 화학식에서 RE는 하나 이상의 희토류 원소(예를 들어, Eu 또는 Gd)이고, M은 Al, Ga, B, In, Sc, Lu, 및 Y의 군으로부터 선택된 하나 이상의 원소이고, E는 S, Se, O, 및 Te의 군으로부터 선택된 하나 이상의 원소이고, x는 0보다 크고, y는 E가 -2의 전하를 갖는다고 가정할 때 상기 화학식에서 전하 균형을 달성하는 값을 갖는다. A luminescent composition of matter is characterized by the formula REM2+xEy, where RE may be one or more Rare Earth elements (for example, Eu or Gd), M may be one or more elements selected from the group Al, Ga, B, In, Sc, Lu, and Y; E is one or more elements selected from the group S, Se, O, and Te; x is greater than zero; and y has the value that achieves charge balance in the formula assuming that E has a charge of −2.
