To obtain efficient blue upconversion laser glasses, upconversion luminescence and mechanisms of Tm(3+)/Yb(3+)-codoped oxyhalide tellurite glasses were investigated under 980 nm excitation. The results showed that upconversion blue and red emission intensities of Tm(3+) first increase, reach its maximum at Tm(2)O(3)%=0.1 mol %, and then decrease with increasing Tm(2)O(3) content. The effect of Tm(2)O(3) content on upconversion intensity is discussed, and possible effect mechanisms are evaluated. The investigated results were conducing to increase upconversion luminescence efficiency of Tm(3+).
为了获得高效的蓝光上转换激光玻璃，研究了在980nm激发下Tm(3+)/Yb(3+)共掺杂卤氧化碲玻璃的上转换发光及其机制。结果表明，Tm(3+)的上转换蓝光和红光发射强度先增加，在Tm2O3含量为0.1mol%时达到最大值，然后随着Tm2O3含量的增加而降低。讨论了Tm2O3含量对上转换强度的影响，并评估了可能的作用机制。研究结果有助于提高Tm(3+)的上转换发光效率。
