中文摘要:

In this paper, we present the luminescent properties of Tm3+∕Ho3+co-doped new glass. A series of silicategermanate glass was prepared by the conventional melt-quenching method. In the Tm3+∕Ho3+co-doped silicategermanate glass, a strong emission of 2 μm originating from the Ho3+:5I7→5I8transition can be observed under conventional 808 nm pumping. The characteristic temperatures, structure, and absorption spectra have been measured. The radiative properties of Ho3+in the prepared glass were calculated. The emission cross section of Ho3+ions transition can reach 4.78 × 10-21cm2 around 2 μm, and the FWHM is as high as 153 nm. The energy transfer efficiency between Ho3+and Tm3+has a large value(52%), which indicates the Tm3+∕Ho3+co-doped silicategermanate glass is a suitable candidate for the 2 μm laser. Moreover, the energy transfer mechanism between Tm3+and Ho3+ions was investigated.
