Abstract

The compositional dependences of Judd-Ofelt intensity parameters Ω1, with t=2,4,6 of Er3+ were investigated systematically in xNa2O.(40-x)B2O3.60SiO 2.0·25Er2O3 (mol%) glasses. The value of Ω2 reveals a maximum around 10 mol% Na2O, inconsistent with a maximum shown at a Na:B ratio of about 1 in some physical properties of sodium borosilicate glasses. Whereas those of Ω4 and Ω5 decrease monotonically with increasing Na2O content. The compositional dependences of the intensity parameters were also compared with those of silicate and borate glasses. It was found that the borosilicate glass compositions can be tailored to obtain those intensity parameter values in both silicate and borate glasses.
