Combining the advantages of ZnO-Al2O_3-SiO_2 system and germinate glass ceramics, Ho~(3+)/Yb~(3+)co-doped ZnO-Al_2O_3-GeO_2-SiO_2 glass ceramics containing ZnAl_2O_4 crystalline phase were successfully prepared by meltcrystallization technique for the first time. Because the tetrahedral [GeO_4] and tetrahedral [SiO_4] are glass network skeleton, Subsequently, the influence of GeO_2 instead of SiO_2 on the hardness and up-conversion luminescence properties of glass ceramic samples is discussed here. Ultimate...
