采用乙酰丙酮（AcAcH）化学改性法制备了光敏掺镧锆钛酸铅（PLZT）凝胶薄膜，并对其傅里叶变换红外（FT-IR）光谱和紫外可见（UV-Vis）光谱进行了测量。结果表明，在PLZT凝胶膜中形成了AcAcH与Ti或Zr的螯合环。在紫外光照射下，螯合环发生光解，导致PLZT凝胶膜在甲醇中的溶解度发生变化。透射电子显微镜（TEM）观察表明，PLZT薄膜经700°C热处理后晶化为钙钛矿相，晶粒尺寸小于等于60 nm。PLZT薄膜表现出磁滞回线和良好的疲劳性能。
The photosensitive lanthanum-doped lead zirconate titanate (PLZT) gel films were prepared by chemical modification with acetylacetone (AcAcH), and their fourier transform infrared (FT-IR) spectra and ultraviolet visible (UV-Vis) spectra were measured. The results show that the chelate rings of AcAcH with Ti or Zr are formed in the PLZT gel films. With irradiation of UV light, the chelate rings are photolyzed, and lead to a change of the solubility of the PLZT gel films in methanol. Transmission electron microscope (TEM) observations show that the perovskite phase is crystallized in PLZT thin film after heat treatment at 700°C, whose grain sizes are less than or equal to 60nm. The PLZT thin films exhibited hysteresis loops and good fatigue properties.
