Abstract: Tb3+ doped transparent molybdate glass ceramics containing CaMoO4 were successful fabricated by melt-quenching technique. The optimal heat-treated system for the glass sample was determined by DSC,XRD and SEM(715℃ for 2. 5 h). The grain size of the glass ceramics gradually increased with the increasing of heat treatment time. The UV-Vis-NIR spectra indicated that the sample transparency was approximately up to 80% in visible light range. The effect of different Tb3+ doping concentration on the luminescence properties of the glass ceramics under the condition of the same heat treatment by fluorescence spectrum. The experimental result indicated that the Tb3+ doping concentration was 7. 0 mol%, the sample has the maximum fluorescence intensity.
