Yb3+-Er3+共掺杂GdOCl粉末的制备及上转换发光性能
Preparation and Upconversion Luminescent Properties of Yb3+-Er3+Co-doped GdOCl Powder
摘要
Abstract
Er,Yb:GdOCl powder was prepared by a high-temperature solid-phase method. The structure, morphology and optical properties were characterized by X-ray diffraction, scanning electron microscopy and fluorescence analysis, respectively. The results indicate that Er,Yb:GdOCl powder can be obtained after calcination for 2h of solid state reaction at 1 000℃. Er,Yb:GdOCl samples in the 520‒560nm region (corresponding to the2H11/2 and4S3/2→4I15/2 transitions of Er3+) and within the 650–670 nm region (corresponding to the4F9/2→4I15/2 transition of Er3+) show intense red light emission lines under 980 nm infrared light excitation. The emission intensity of the red and green light firstly increases and then decreases gradually with increasing Er3+ doping concentration, showing the energy migration of Er,Yb:GdOCl. In addition, the possible mechanism of red light emission and energy transfer between Yb3+ and Er3+ was also dicussed.关键词
