摘要：

This paper describes an investigation of the crystalline morphology and photoluminescent properties of BaY2ZnO5 Eu3+ powders using microwave assisted sintering For comparison, the properties of BaY2ZnO5 Eu3+ powders prepared by a solid-state reaction in a conventional furnace were also investigated The results showed that the formation time of the single phase for BaY18Eu0 2ZnO5 powders sintered at 1250 degrees C in the microwave furnace is significantly reduced to 1 h, and the emission spectra of BaY18Eu0 2ZnO5 powders excited at 395 nm exhibit a maximum peak assigned to D-5(0)-> F-7(2) transition. In addition, the emission intensity of the prepared powder is definitely enhanced, compared to that sintered at 1250 degrees C/10 h in a conventional sintering furnace (C) 2010 Elsevier B V All rights reserved
