摘要

在457nm、488nm和514nm激发下，采用恒定激光z扫描技术研究了两种配合物的热光学效应。结合实验曲线和理论公式计算了热光学系数dn/ dnd和热致非线性折射率n2值。结果表明，热致非线性光学性质与分子结构和激发波长有关。铜配合物的热光学系数和热致非线性折射率值较高，且对激发波长不敏感。Pd配合物的热致非线性光学值随激发波长的增加而减小。这是由分子结构引起的吸收光谱差异决定的。

Comparative study on the thermo-induced nonlinear optical properties of metal-organic complexes

Thermo-optical effects of two types of complexes are investigated using constant laser z-scan technique under 457nm,488nm and 514nm excitation.Thermo-optical coefficients dn/dTand thermo-induced nonlinear refractive indexes n2values are calculated by combination of experimental curves and theoretical formula.By comparing the results,it is found that the thermo-induced nonlinear optical properties are dependent on the molecular structures and excitation wavelength.The thermo-optical coefficient and thermo-induced nonlinear refractive index value of Cu complexes are higher,and are insensitive to the excitation wavelength.The thermo-induced nonlinear optical values of Pd complexes are decreased with the increase of the excitation wavelength.It is decided by the absorption spectra difference induced by the molecular structure.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
