Abstract

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.
