摘要
采用明胶网格沉淀法,成功制备了共掺铈、铽的磷酸镧纳米颗粒。用透射电子显微镜、X射线衍射仪及TG对产物的形貌、结构和热稳定性进行了表征。并研究了铈、铽含量,煅烧温度及煅烧时间对LaPO4∶Ce,Tb纳米粒子发光性质的影响。
Ce, Tb - doped LaPO4 nanopartieles were successfully prepared by a gel - network precipitation process. The products were characterized by TEM and XRD. The effects of calcination temperature and time as well as concentration of Tb^3＋ and Ce^3＋ on the luminescence intensity of LaPO4 ： Ce, Tb nanoparticles were investigated.
