Abstract
The MgO-Ga2O3-SiO2 glass-ceramic (GC) containing MgGa2O4 nanocrystals and glasses doped with Eu3+ ions were prepared by the sol-gel method. The down-conversion and up-conversion luminescence (UCL) properties were studied. The results indicated that the relative intensity of f-f transitions of Eu3+ decreased in contrast with that of charge transfer (CT) absorption with the increase in heating temperature. Using a Xe lamp and 800Â nm femtosecond (fs) laser excitation, strong red luminescence of Eu3+ in MgO-Ga2O3-SiO2 glasses and GC was observed.
