| 摘 要： | Intense 2.7-μm emissions are obtained from Er3+/Nd3+ co-doped tellurite glass samples under the 808-nm laser diode excitation.According to the absorption spectra,Judd-Ofelt parameters and radiative transition probabilities are calculated and analyzed using the Judd-Ofelt theory.The spectroscopic properties and energy transfer mechanism between Er3+ and Nd3+ are analyzed.The effects of OH- content on the spectroscopic properties of Er3+/Nd3+ co-doped samples are discussed.The obtained results indicate that Er3+/Nd3+ co-doped tellurite glass can significantly develop optical properties of 2.7-μm emission,if OH- exoups can be effectivelv eliminated.
