Abstract
(5,10,15,20-Tetraphenylporphyrinato)-copper(II) (TPP-Cu) are synthesized, and characterized by X-ray single crystal diffraction. TPP-Cu doped polymethylmethacrylate (PMMA) thin film on quartz substrate were prepared by spin-coating method. The morphology of the film were investigated by scanning electron microscopy. The nonlinear refractive properties of the film were studied using closed aperture Z-scan technique by picosecond (PS) laser pulses at different irradiance at wavelength 1064Â nm. The nonlinear refraction coefficient n2I value of the film were determined to be 1.28Â ÃÂ 10â12Â m2/W, this making them ideally suited to the applications in the field of all-optical switches.
