Description

Optical properties of Ce3+-doped Li2O-B2O3-SiO2 glasses prepared in inert atmosphere have been examined. Clear splitting of 4f-5d excitation bands is observed in these glasses at room temperature. The emission decay constant depends on the excitation and emission energy, indicating the site distribution of Ce3+ in the random glass matrix. The absorption energies of Ce3+ are independent of the optical basicity, suggesting that the emission is affected by the local basicity of random network. The present findings provide the basic concepts for designing Ce-doped oxide glass for luminescent applications.
