Abstract:
1. A light emitting device, comprising: a pair of electrodes; a light emitter placed between the electrodes; and a semiconductor laminated to be adjacent to the light emitter, wherein the semiconductor includes one of a chalcopyrite and an oxychalcogenide, wherein a constituent material of the light emitter is represented by ZnS:A (acceptor), D (donor), and at least one material is selected from Au, Ag, Cu, N, O, S, Se, and Te for the A (acceptor), and at least one material is selected from Al, Ga, In, F, Cl, Br, I, O, S, Se, and Te for the D (donor), wherein the chalcopyrite is represented by a I-III-VI wherein the at least one material corresponding to the A (acceptor) and the at least one material D (donor) are diffused from the chalcopyrite or the oxychalcogenide due to a heat treatment.
