The study of the fluorescent glass filler for composite resin

Abstract

We prepared the fluorescent glass filler for the easily detective composite resin. The borosilicate glasses containing various rare earth oxide, e.g. europium, were prepared and applied for the composite resin. The composite resin using glass fillers containing europium and some other rare earth oxides showed clear fluorescence emission under blue and UV excitation without affecting on the color of the glass filler and the esthetic appearance.
