RE2O2CN2:Eu3+ (RE = Y, La) phosphors were prepared from the mixture of RE(OH)3:Eu3+ and urea after calcination under N2 flow. Through the optimization of reaction conditions, including content of urea and heat-treatment temperature, single-phase La2O2CN2:Eu3+ and Y2O2CN2:Eu3+ could be obtained without any impurities. The photoluminescence properties of obtained La2O2CN2:Eu3+ and Y2O2CN2:Eu3+ were investigated in detail.
