研究了Tm3+/Er3+/Yb3+共掺杂氧化卤化物碲酸盐玻璃在980 nm激发下，通过频率上转换和能量转移的蓝、绿、红发射过程。在室温下同时观察到强烈的蓝色（476nm）、绿色（530和545nm）和红色（656nm）发射。蓝色（476 nm）的发射来自于Tm3+的(1)G(4)-> H-3(6)跃迁。Er3+的H-2(11/2)-> I-4（15/2）、S-4(3/2)-> I-4（15/2）和F-4(9/2)-> I-4（15/2）上转换荧光分别为绿色（530和545 nm）和红色（656nm）。评估了能量传递过程和可能的上转换机制。(C) 2005 Elsevier B.V.版权所有
Blue, green and red emissions through frequency upconversion and energy transfer processes in Tm3+/Er3+/Yb3+-codoped oxyhalide tellurite glass under 980 nm excitation are investigated. The intense blue (476 nm), green (530 and 545 nm) and red (656 nm) emissions are simultaneously observed at room temperature. The blue (476 nm) emission was originated from the (1)G(4)-> H-3(6) transition of Tm3+. The green (530 and 545 nm), and red (656 nm) upconversion luminescences were identified from the H-2(11/2)-> I-4(15/2), S-4(3/2)-> I-4(15/2), and F-4(9/2)-> I-4(15/2) transitions of Er3+, respectively. The energy transfer processes and possible upconversion mechanisms are evaluated. (C) 2005 Elsevier B.V. All rights reserved.
