PHOSPHORS WITH NARROW GREEN EMISSION

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 T...

Beschreibung
Zusammenfassung:	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.
