摘要 | Er, Yb: (LaLu)2O3 ceramic powders were prepared via citric combustion method. XRD patterns show that the production prepared at 1 000 is pure phase of (LaLu)2O3. Er, Yb: (LaLu)2O3 and Er: (LaLu)2O3 ceramic was synthesized by cold isostatic-vacuum sintering method. The structural and spectroscopic properties of the ceramics were investigated in detail. The upconversion 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 radiant transitions of 4S3/2(2H11/2)4I15/2 and 4F9/24I15/2 of Er3+, respectively. The energy transfer process and upconversion luminescence mechanism of Er3+-Yb3+ in co-doped system were studied. 2018, Science Press. All right reserved. |
