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: M a (Al,B) b Si c N d O e :Eu m , R n , 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<d<5, 0<e<0.1, 0<m<0.05, 0<n<0.1 and 1<c/b<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 of 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. |
