摘要
采用化学溶液沉积法在Pt/TiO2/SiO2/Si衬底上制备LaxSr1-xCoO3(简称LSCO)导电薄膜,对不同的La/Sr比以及掺入Ni的情况下LSCO导电薄膜的红外光学性质进行了比较研究。结果表明:LSCO薄膜的红外吸收与La/Sr的化学计量比值有关,当La/Sr为1∶1时,LSCO薄膜的红外吸收最强;在LSCO薄膜中掺入一定量的Ni后,其红外光吸收将会增强,这说明掺Ni有利于提高基于LSCO薄膜电极的铁电探测器的红外吸收能力。
La Sr1-3 CoO3 （LSCO）thin films were deposited on Pt/TiO2/SiO2/Si substrates by chemical solution routes. Infrared optical properties of LSCO thin films with different La/Sr stoichiometric ratio and that of the LSCO thin films doped nickel were studied. It is found that infrared absorption is relevant to the La/Sr stoichiometric ratio. When La/Sr value is 1 ： 1 the infrared absorption of LSCO thin films is at the maximum. The infrared absorption of LSCO thin films doped nickel will increase.
