چکیده انگلیسی
The Tm3+/Ho3+ co-doped silicate-germanate glasses with good thermal properties were synthesized by high temperature melting method. 2.0â¯Î¼m emissions with broad effective half-width (231.5â¯nm) were successfully obtained in present Tm3+/Ho3+ co-doped glasses without obvious quenching upon excitation of a commercial 808â¯nm laser diode. To further understand 2â¯Î¼m fluorescence behaviors of the prepared glasses, energy transfer mechanism, efficiency, rate and microparameters from different levels of Tm3+ to Ho3+ ions have been obtained and discussed. In short, the Tm3+/Ho3+ co-doped silicate-germanate glass with excellent spectroscopic properties might be an attractive host material for 2â¯Î¼m broadband solid laser.
