چکیده انگلیسی
The nonlinear optical properties of phenothiazine-iodine (PTZ-I) charge transfer complexes (CTC) in three different proportions were investigated by z-scan set up using Nd: YAG laser at 532â¯nm wavelength, 7â¯ns pulse width and 10â¯Hz repetition rate as excitation source. The interaction between phenothiazine and iodine was analysed using FTIR spectroscopy. The morphological changes after the formation of CTC were observed with the help of scanning electron microscopy and optical microscopy. The CTC system displayed an absorption in the UV-Visible region, which is attributed to the charge transfer between constituents. Optical nonlinearity was observed to be maximum when the molar ratio between phenothiazine and iodine is 1:1, and it strongly depends on the electron donor-acceptor proportion. Optical limiting threshold values of the studied samples are comparable to many reported values. The excellent nonlinear optical properties exhibited by PTZ-I CTC make them promising candidates in nonlinear optical applications.
