Determination of the linear optical properties of polymer+phtalocyanine+NLO thin films

Key Words: polymer, phthalocyanine, NLO, thin film, refractive indexIn this study polymer thin films containing polymer and phthalocyanine -DAN arecovered over glass conveyor by submersion technique. The necessary solution forthis process contains polycarbonate (bis-phenol-A-BPAPC), dichloromethane,phthalocyanine and DAN in appropriate amount. In the process of covering films onglass conveyor vertical speed submersion technique is used in 84mm/min. Onelayeredfilms with different characteristics are prepared.In defining the optical characteristics of films UV spectrometer is used. Absorption,transmission and reflection data of all films are compared. By using these data thethickness and refractive index of films are calculated.According to the results obtained from the UV spectrometer the medium oftransmission is 90 ? 92 %. The data show that light is greatly absorbed in UV area.The transfusion cutting rate in DAN added polymers slides to long wavelength. Thecutting rate for polymer samples containing polymer and phthalocyanine is about264nm.
