摘 要：Neodymium-substituted bismuth titanate （Bi3NdTi3O12, BNT） thin films were prepared on quartz substrates by a metal-organic solution deposition process. The crystalline structure was evaluated by X-ray diffraction. Waveguide property was investigated by using prism coupling technique and optical transmittance measurement. The optical nonlinearities of the film were measured by the top-hat Z-scan techniques and a large positive nonlinear refractive index, nonlinear refractive coefficient and two-photon absorption coefficient were determined to be 3.84×107 esu, 0.7523 cm2/GW and 4.81×104 cm/GW, respectively. These results reveal that the BNT film may be a kind of new multifunctional materials.
