| 摘要 |
An oxynitride orange-red fluorescent substance and a light-emitting film or sheet and a light-emitting device comprising the same are disclosed. The chemical formula of the oxynitride orange-red fluorescent substance is M m A a Si x N y O z : dR in which the element M is one or more of the elements Ca, Sr and Ba, the element A is Al or a mixture of Al with one or more of the elements Ga, La, Sc and Y, the element R is one or more of the elements Ce, Eu and Mn, and chemical formula meets 0.8‰¤m‰¤ 1.2, 1 <a<1.7, 1 <x<1.7, 3<y<4.2, 0<z<0.7, and 0.001 ‰¤d‰¤0.2. The oxynitride orange-red fluorescent substance can emit orange-red light under the excitation of a radiation source, and with a relatively high luminous efficiency, the oxynitride orange-red fluorescent substance meets the demands for high color rendering performance and low color temperature of a white LED. |
