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