中文摘要	by conventional melting and quenching methods, 3yb(2)o(3)-0.2tm(2)o(3)-xho(2)o(3) (wt%, x = 0.2 similar to 1.2) was doped into an easily fiberized tellurite glass with composition of 78teo(2)-10zno-12na(2)o (mol%) to form yth-tzn78 glasses. under 976 nm excitation, the direct sensitizing effect of yb ions (yb -> ho) and indirect sensitizing and self-depopulating effects of tm ions (yb -> tm -> ho) were found to present intense red upconversion emission at 657 nm (red, ho: f-5(5) -> i-5(8)) and were responsible for the absence of the usually observed 484 nm emission (blue, tm: (1)g(4) -> h-3(6)). regardless of the dopant concentration of ho ions, the intensity of the red emission at 657 nm (red, ho: 5f5. 5i8) is about three times stronger than that of the green one at 543 nm (green, ho: s-5(2) -> i-5(8)). for this certain red emission at 657 nm, 0.4 wt% ho2o3-doped yth-tzn78 glass was found to present the highest emission intensity and is therefore determined as a promising active tellurite glass for red fiber laser development.
