摘要：
The glass transition temperature (T),crystallization onset temperature (T) and Raman scattering spectra of new tellurite glasses were studied as the function of glass composition.With the introduction of other metal oxides such as NbO,BaO and WO,Ttemperature increases,the intensity of exothermal peaks decreases,and thermal stability of tellurite glass improves.It was found that more TeOunits transformed into TeOunits and non-bridging oxygen atoms decreased with the incorporating other metal oxides in glassy network,when the content of TeOwas fixed.Appearance of peak at 920 cmbroadens the Raman bandwidth of tellurite glasses,which is very useful realize high efficient broadband fiber Raman amplifiers.
