利用脉冲激光法(PLD)制备了镧钙掺杂的钛酸铅(Pb0.8La0.1Ca0.1) Ti0.975O3(PLCT)热释电薄膜,通过广角X射线衍射(XRD)研究了薄膜的相组成,利用X射线镜面反射表征TiO2种子层的厚度,通过X射线衍射及ω扫描研究了TiO2种子层对薄膜晶体学织构及其弥散程度的影响.结果表明,合适的晶化温度可以获得纯钙钛矿相的PLCT热释电薄膜.种子层的引入改变了薄膜的织构类型,无种子层时,薄膜倾向于形成(100)织构;而引入TiO2种子层则有利于薄膜(301)织构的形成.

Lanthanum calcium-doped lead titanate (Pb0.8La0.1Ca0.1) Ti0.975O3 (PLCT) pyroelectric films were prepared by pulsed laser (PLD), the phase composition of the films was studied by wide-angle X-ray diffraction (XRD), the thickness of TiO2 seed layer was characterized by X-ray specular reflection, and the effect of TiO2 seed layer on the crystallographic texture of thin film crystallography and its diffusion degree was studied by X-ray diffraction and ω scanning. The results show that PLCT pyroelectric films of pure perovskite phase can be obtained at a suitable crystallization temperature. The introduction of the seed layer changes the texture type of the film, and when there is no seed layer, the film tends to form a (100) texture; The introduction of TiO2 seed layer was conducive to the formation of thin film (301) texture.
