摘要

In this paper a set of (95-x)P2O5-xB2O3-4·9Na2O-0·1Er2O3 (x=5, 10, 15, 20 mol%) samples was prepared using a conventional melt-quenching technique. A glass ceramic phase was confirmed by x-ray diffraction. The glass containing 20 mol% B2O3 shows a high thermal stability with a value AT=T_c-T_g exceeding 100°C, where T_g and T_c are the glass transition and crystallization onset temperatures. From the absorption edge studies, the value of the optical band gap E_(opt) has been evaluated. The fundamental absorption edge for all the glasses was analyzed and the Judd-Ofelt parameters (Ω2, Ω4 and Ω6) were obtained. The PL intensity, the PL life time and the quantum efficiency relative to the ~1I_(13/2)→~4I_(15/2) (1530 nm) transition of Er~(3+) were all found to decrease with the addition of B2O3.
