Abstract:
The present invention provides a phosphor with a preferred orientation represented by the following formula: A2[MF6]:Mn4+, wherein A is selected from a group consisting of Li, Na, K, Rb, Cs, and NH4, M is selected from a group consisting of Ge, Si, Sn, Ti, and Zr. The preferred orientation is a (001)/(011) preferred orientation. The present invention also provides a method for fabricating the above phosphor. The present invention further provides a light-emitting element package structure employing the same.
