For this study, different alkali carbonates (Li2CO3, Na2CO3, and K2CO3) were added to a Eu3+ activated YInGe2O7 phosphor synthesized using conventional sintering and microwave-assisted sintering. The morphology and photoluminescence properties of YInGe2O7:Eu3+ phosphors were investigated and discussed. When the alkali ions were introduced into YInGe2O7:Eu3+ phosphors, the excitation peaks of phosphors were shifted to a short wavelength because the addition of alkali ions may increase the oxygen vacancy in YInGe2O7:Eu3+ phosphors. Additionally, the best enhanced luminescent properties in YInGe2O7:Eu3+ phosphors were obtained through the addition of Li+ ion.
