This paper describes an investigation of the crystalline morphology and photoluminescent properties of YInGe 2 O 7 powders doped with different Eu 3+ concentrations using microwave assisted sintering and conventional sintering. X-ray powder diffraction analysis confirmed the formation of monoclinic YInGe 2 O 7 structure as YInGe 2 O 7 :Eu 3+ powders were sintered at 1200°C in microwave furnace for 1h, and the raw material phase of Y 2 O 3 was observed when Eu 3+ concentration was below 30mol%. Scanning electron microscopy showed microwave assisted sintering results in smaller particle size and more uniform grain size distribution. In the photoluminescent (PL) studies, the concentration quenching effect was observed under the excitation at 393nm, but not under the excitation at CTS band. The 5 D 0 → 7 F 2 transition (620nm), exhibits a non-exponential decay behavior as YInGe 2 O 7 :Eu 3+ powders were sintered by microwave with the Eu 3+ concentration higher than 50mol%.
