Effect of Charge Compensation on Emission Spectrum of SrZnO_2:Eu~(3+) Phosphor

SrZnO2:Eu3+,M+(M=Li,Na,K) red-emitting phosphors were prepared by low-temperature combustion synthesis(LCS).The effect of the sensitizer Li+,Na+ and K+ on the emission spectra of ZnSrO2: Eu3+ phosphor was studied.It was presented that the emission spectrum intensity of SrZnO2:Eu3+ phosphor was enhanced by co-doped with alkali metal ions,and the relative luminescence intensity was the highest while n(Eu3+):n(Li+) was 1:3.The theoretical reason for the above results was analyzed.
