Er,Yb:(LaLu)2O3透明陶瓷制备及上转换发光性能
Preparation of Er,Yb:(LaLu)2O3 Ceramic and Its Upconversion Luminescent Properties
摘要
Abstract
Er,Yb:(LaLu)2O3 ceramic powders were prepared via citric combustion method. XRD patterns show that the production prepared at 1000 ℃ is pure phase of (LaLu)2O3. Er,Yb:(LaLu)2O3and Er:(LaLu)2O3ceramic was synthesized by cold isostatic-vacuum sintering method. The structural and spectroscopic properties of the ceramics were investigated in detail. The upconve-rsion emission increases obviously when 5% Yb3+ and 10% La3+ are doped in the ceramic compared with the samples without Yb3+ and La3+ doping. The upconversion fluorescence spectra show that the intense green and red emissions located at around 564 nm and 661 nm are attributed to the ra-diant transitions of 4S3/2(2 H11/2)→4I15/2 and 4F9/2→4I15/2 of Er3+,respectively. The energy transfer process and upconversion luminescence mechanism of Er3+-Yb3+ in co-doped system were studied.关键词
