Abstract
Intense 2.7-\mu m 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-\mu m emission, if OH groups can be effectively eliminated.
