摘要：
A sol-gel method for the synthesis of nanosized powders of yttrium disilicate doped with Tb3+ is presented. The influence of grain size and annealing temperature on the structure and luminescence properties of the materials obtained has been investigated. The preparation of glass-ceramic composite has been also described. The effect of incorporating the nanocrystals into sol-gel silica glasses on their physicochemical properties has been shown and discussed. A lack of influence of the annealing above 1300 degrees C on the lifetimes measured for the nanocrystals embedded in the glass, as compared to the Y2Si2O7:Tb3+ powders, has been observed.
