Compound of phosphor and the manufacturing method thereof

A manufacturing method of a metal oxonitridosilicate phosphor, comprising the steps of:

• mixing a first reactant comprising Sr, a second reactant comprising Al, a third reactant comprising Si, a fourth reactant comprising Eu, and a fifth reactant comprising Mn to form a mixture;
• and
• forming the mixture into a metal oxonitridosilicate phosphor with a general formula M5−z−a−bAl3+xSi23−xN37−x−2aOx+2a:Euz,Mnb by solid-state reaction at high pressure, wherein 0≦x≦7;
• 0≦a≦1;
• 0<z≦0.3;
• and 0<b≦0.3, and the phosphor emits a fluorescence with a wavelength ranging from 480 nm to 700 nm when excited by a light source with a wavelength ranging from 300 nm to 460 nm.
