An object is to provide a novel light emitting material. Another object is
to provide a light emitting device and an electronic device with reduced
power consumption. Still another object is to provide a light emitting
device and an electronic device which can be manufactured at low cost.
Provided is a light emitting element including a base material, a first
impurity element, a second impurity element, and a third impurity
element. The base material is one of ZnS, CdS, CaS, Y.sub.2S.sub.3,
Ga.sub.2S.sub.3, SrS, BaS, ZnO, Y.sub.2O.sub.3, AlN, GaN, InN, ZnSe,
ZnTe, and SrGa.sub.2S.sub.4; the first impurity element is any of Cu, Ag,
Au, Pt, and Si; the second impurity element is any of F, Cl, Br, I, B,
Al, Ga, In, and Tl; and the third impurity element is any of Li, Na, K,
Rb, Cs, N, P, As, Sb, and Bi.
