| Abstract: Combining the advantages of ZnO-Al2O3-SiO2 system and germinate glass ceramics, Ho3+/Yb3+ co-doped ZnO-Al2O3-GeO2-SiO2 glass ceramics containing ZnAl2O4 crystalline phase were successfully prepared by melt-crystallization technique for the first time. Because the tetrahedral[GeO4] and tetrahedral[SiO4] are glass network skeleton, Subsequently, the influence of GeO2 instead of SiO2 on the hardness and up-conversion luminescence properties of glass ceramic samples is discussed here. Ultimately, when the quantity of GeO2 instead of SiO2 was 10.55%(w/w), comprehensive performance of the glass ceramic samples were optimum. Under the 980 nm pump light excitation, a strong green emission (546 nm) and a weak red emission (650 nm) are observed. The effect of different doped ratios of Ho3+/Yb3+ on the up-conversion luminescence of samples was studied. The experimental results indicated that the luminescence intensity reaches a maximum when the doped ratios of Ho3+:Yb3+ is 1:11 and the samples have potential application on green up-conversion luminescence material. |
