Beschreibung
Zusammenfassung:	A light-conversion material and a light-emitting device and a display device including the same are provided. The light-conversion material is represented by formula (I): MmDdAaCcEeGg:Rr (I). Wherein M is Ca, Sr, or Ba; D is Zn, Cd, or a combination thereof; A is B, Al, or Ga; C is Si; E is O, S, or Se; G is N, P, As, Sb, or Bi; and R is Eu, Sm, or Yb. The formula (I) is satisfied by 0.5≤m≤2; 1≤d≤4; 0≤a≤2; 0.1≤c≤3.5; 0.1≤e≤4; 0.5≤g≤5.5; and 0.1≤r≤1.
