摘要
用ＦＴＩＲ分析，结合ＤＳＣ、ＸＲＤ、ＡＦＭ实验结果，展示了ｓｏｌ－ｇｅｌ法制备ＢａｘＳｒ１－ｘＴｉＯ３（ＢＳＴ）薄膜热演化过程的化学机制．研究表明：螯合剂ＨＡＣＡＣ的引入减缓钛醇盐水解速率、改善晶化途径、降低结晶起始温度，从而制得了晶化完善、致密无裂纹的ＢＳＴ薄膜．
FTIR analysis combined with DSC, XRD and AFM experiments was used to study on the chemical mechanism of thermal evolution for BaxSrl-xTiO3 (BST) thin films derived by sol-gel method. Acetylacetone(HAcAc) was introduced as a chelating agent to reduce a rapid hydrolysis rate of Ti-alkoxide, to improve its crystallization path, to decrease its crystallization temperature. And then the densified and crack-free BST thin films with better crystallization were fabricated.
