摘要: 采用改进的溶胶-凝胶法制备出稀土铕掺杂PZT(PEZT)的纳米粉,粒径约为20nm.由XRD分析了Eu的掺入对PZT微观结构的影响,确定了Eu的最佳掺入量≤7%,分析了Eu在PZT中的占位情况.

Abstract: Rare earth cation Eu3+ doped PZT nanopowders (PEZT) were produced by a mod- ified sol-gel method, and their particle sizes were between 10~20nm. The effect of Eu3+ on the microstructure of PZT powders was analyzed by using XRD, and the position status of Eu3+ in crystal unit cell of PZT was also analyzed. The results show that the appropriate content of Eu3+ added into PZT is≤ 7%.

Key words: PZT, sol-gel, rare earth, nanopowders
