摘要
采用sol-gel工艺制备了Pb0.97La0.02(Zr0.95Ti0.05)O3反铁电厚膜材料,研究了不同前驱体溶剂(乙酸和乙二醇乙醚)对反铁电厚膜介电性能的影响。结果表明:由乙二醇乙醚作为前驱体溶剂制备的反铁电厚膜材料,在室温下反铁电态稳定,其AFE-FE相的相变电场强度为184.05×103V/cm,FE-AFE相的相变电场强度为68.24×103V/cm,饱和极化强度为88.8×10-6C/cm2。
Pb0.97La0.02（Zr0.95Ti0.05）O3 antiferroelectric thick films were fabricated via the sol-gel process.The effects of precursor solvent（acetic acid and 2-ethoxyethanol） on the dielectric properties of the Pb0.97La0.02（Zr0.95Ti0.05）O3 antiferroelectric thick films were studied.The results show that the Pb0.97La0.02（Zr0.95Ti0.05）O3 antiferroelectric thick films obtained by employing 2-ethoxyethanol as the precursor solvent show a stable antiferroelectric state at room temperature,while their saturated polarization is 88.8×10-6 C/cm2 and the fields for their AFE-FE and FE-AFE phase transition are 184.05×103 V/cm and 68.24×103 V/cm,respectively.
