| 英文摘要 | (na1-xkx)(0.5)bi0.5tio3 (nkbt) (x = 0.1, 0.2, and 0.3) thin films with good surface morphology and rhombohedral perovskite structure were fabricated on quartz substrates by a sol-gel process. the fundamental optical constants (the band gaps, linear refractive indices and absorption coefficients) of the films were obtained through optical transmittance measurements. the nonlinear optical properties were investigated by z-scan technique performed at 532 nm with a picosecond laser. a two-photon absorption effect closely related with potassium-doping content was found in thin films, and the nonlinear refractive index n(2) increases evidently with potassium-doping. the real part of the third-order nonlinear susceptibility chi((3)) is much larger than its imaginary part, indicating that the third-order optical nonlinear response of the nkbt films is dominated by the optical nonlinear refractive behavior. these results show that nkbt thin films have potential applications in nonlinear optics.
