Abstract
Intense 2.7-Μm emissions are obtained from Er<sup>3+</sup>/Nd<sup>3+</sup>
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 Er<sup>3+</sup> and
Nd<sup>3+</sup> are analyzed. The effects of OH<sup>-</sup> content on the spectroscopic
properties of Er<sup>3+</sup>/Nd<sup>3+</sup> co-doped samples are discussed. The
obtained results indicate that Er<sup>3+</sup>/Nd<sup>3+</sup> co-doped tellurite
glass can significantly develop optical properties of 2.7-Μm emission, if
OH<sup>-</sup> groups can be effectively eliminated.
