摘要：
New series of rare earth doped halogeno-phosphate glasses with compositions: (100-x-y) NaPO3 - x PbCl2- y BaCl2: LnF(3) (Ln=Er or Ho) were prepared and characterized. These glasses exhibit a good resistance against devitrification. Spectroscopic analyses based on Judd-Ofelt theory were performed. Starting from absorption spectra, the oscillator strengths and the intensity parameters Omega(2), Omega(4) and Omega(6) have been evaluated, and various radiative properties like radiative transition probability, branching ratio and radiative lifetime were determinated. Spectroscopic quality factor (Omega(4)/Omega(6)) has been evaluated to understand the lasing efficiency of these materials. These glasses could be used as lasing materials and offer prospects for photonics applications.
