Pb_(1-3x/2)Eu_x(Zr_(0.52),Ti_(0.48))O_3纳米粉的溶胶-凝胶合成

Synthesis of Pb_(1-3x/2)Eu_x(Zr_(0.52),Ti_(0.48))O_3 Nanopowers by Sol-Gel Methods

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．

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%.
