Abstract
In this work, Eu2+ doped CaAlSiN3 red-emitting nitride phosphors were synthesized for the first time from less-expensive and air-stable entire oxides raw materials, CaCO3, SiO2, Al2O3, and Eu2O3, through a common carbothermal reduction and nitridation (CTRN) method. The synthetic reaction processes involving in this CTRN route and the phase components, photoluminescent properties for the resultant CaAlSiN3:Eu2+ nitride phosphors were investigated in detail. The presented synthesis route using cost-effective entire oxides raw materials for preparation of CaAlSiN3:Eu2+ nitride phosphors shows promising prospect in promoting the application of CaAlSiN3:Eu2+ nitride phosphors in solid state lighting.
