Abstract
The compositional dependences of Judd-Ofelt intensity parameters Omega(t) w ith t=2,4,6 of Er3+ were investigated systematically in xN(n)2O .(40-x)B2O3 . 60SiO(2). 0.25Er(2)O(3) (mol%) glasses The value of Omega(2) reveals a ma ximum around 10 mol% Na2O, inconsistent with a maximum shown at a Na:B rati o of about I in some physical properties of sodium borosilicate glasses. Wh ereas those of Omega(4) and Omega(6), decrease monotonically, with increasi ng Na2O content. The compositional dependences of the intensity, parameters were also compared with those of silicate and berate glasses. It was found that the borosilicate glass compositions can be tailored to obtain those i ntensity parameter values in both silicate and borate glasses.
