Excitation power dependence of Eu3+ photoluminescence in barium borate glass

Eu3+-doped barium borate glasses are analysed for their optical and excitation power dependent luminescence properties. The glasses, doped with different concentrations of the lanthanide ion Eu3+, provide photoluminescence quantum efficiencies higher than 80% and, show a bright luminescence in the red spectral range, making them attractive for lighting applications.
