Crystalline morphology and photoluminescent properties of YInGe2O7:Eu3+ phosphors prepared from microwave and conventional sintering

摘要: Abstract This paper describes an investigation of the crystalline morphology and photoluminescent properties YInGe 2 O 7 :Eu 3+ powders using microwave assisted sintering. For comparison, sintered at 1200 °C in conventional furnace for 10 h were also investigated. X-ray powder diffraction analysis confirmed formation monoclinic without second phase or phases starting materials as :50 mol% Eu 1 h. Scanning electron microscopy showed smaller particle size more uniform grain distributions are obtained by In PL studies, both conventionally emitted a maximum luminescence centered 620 nm under excitation 393 nm with similar luminescent intensity. The results show that processing has potential to reduce time required energy input production phosphors sacrificing photoluminescence.
