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.
