Abstract

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 BaY1.8Eu 0.2ZnO5 powders sintered at 1250 °C in the microwave furnace is significantly reduced to 1 h, and the emission spectra of BaY 1.8Eu0.2ZnO5 powders excited at 395 nm exhibit a maximum peak assigned to 5D07F 2 transition. In addition, the emission intensity of the prepared powder is definitely enhanced, compared to that sintered at 1250 °C/10 h in a conventional sintering furnace.
