Sr 2 Si 5 N 8 :Eu 2+ nitride phosphors application for light emitting diodes were synthesized for the first time using less‐expensive and air‐stable entire oxides raw materials, Sr CO 3 , SiO 2 , and Eu 2 O 3 , through a carbothermal reduction and nitridation (CTRN) route. The reaction dynamic processes of the CTRN route and the phase components, photoluminescent properties, quantum efficiency as well as thermal stability for the resultant Sr 2 Si 5 N 8 :Eu 2+ phosphors were investigated in detail. High‐crystalline pure Sr 2 Si 5 N 8 :Eu 2+ red‐emitting phosphor with acceptant luminescent performances could be obtained through finely controlling addition amount of carbon reductant agent and carefully removing the residual carbon without oxidation damage. An economic route is outlined in this work for the synthesis of nitride phosphors using cost‐effective entire oxides raw materials, thereby driving the development and practical application of nitrides phosphors.
