Concentration dependence of PLE spectra of xSnO-(25-x)SrO-75B2O3 glasses.
(a) PLE spectrum (emission at 3.13 eV) of 1.5SnO-23.5SrO-75B2O3 glass together with deconvoluted bands: higher energy band A and lower energy band B. (b) Peak position and area of B band as a function of SnO amount in PLE spectra of xSnO-(25-x)SrO-75B2O3 glasses.
