Red light-emitting nitride material, and light-emitting part and light-emitting device comprising the same
Disclosed are a red light-emitting nitride material, a light-emitting part and a light-emitting device comprising the same. The General Formula of the light-emitting material is: Ma(Al,B)bSicNdOe:Eum, Rn, wherein M is at least one of the alkaline earth metal elements Mg, Ca, Sr, Ba and Zn; R is at least one of the rare earth elements Y, La, Ce, Gd and Lu; and 0.9≰a<1.1, 0.9≰b≰1, 1≰c≰1.5, 2.5<1.5. The light-emitting material can be effectively excited by a radiation light having a wavelength below 500 nm, and then emits a visible red light having a wide spectrum from 500 nm to 780 nm. The light-emitting material of the present disclosure has the characteristics of high light-emitting efficiency, good temperature properties and a wide half-width etc., and the material can be used alone or in combination with other light-emitting materials for making high performance light-emitting devices.
