Resumo |
To obtain efficient blue upconversion laser glasses, upconversion luminescence and mechanisms of Tm3+/Yb3+-codoped oxyhalide tellurite glasses were investigated under 980nm excitation. The results showed that upconversion blue and red emission intensities of Tm3+ first increase, reach its maximum at TM2O3% =0.1 mol%, and then decrease with increasing Tm2O3 content. The effect of TM2O3 content on upconversion intensity is discussed, and possible effect mechanisms are evaluated. The investigated results were conducing to increase upconversion luminescence efficiency of Tm3+. (c) 2005 Elsevier B.V. All rights reserved. |
