Time-dependent emission property of SnO-SrO-B2O3 glasses and (Sn0.02Sr0.98)B6O10 crystal.
Streak images of 1.0SnO-24.0SrO-75B2O3 glass (a) and (Sn0.02Sr0.98)B6O10 crystal (b) excited by photon energy 4.86 eV. (c) Time-dependence of emission peak energy of xSnO-(25-x)SrO-75B2O3 glasses. Radiative relaxation of nanosecond order indicates relaxation from S1 excitation state.
