Paper Abstract

In present work we report the analysis of thin films and targets from new stilbazolium dye E-4-(2-(4- hydroxynaphthalen-1-yl)vinyl)-1-octylquinolinium iodide (D1) deposited by Pulsed Laser Deposition (PLD) technique using high power UV TEA N2 laser. The thin films are deposited onto substrates – KBr, 316L SS alloy, optical glass and aluminum foil. The films were characterized by FTIR spectroscopy, bright field microscopy, fluorescence microscopy and atomic force microscopy (AFM) analysis. FTIR spectroscopic analysis of thin films and target material shows small differences between deposited films and native substance. The films are found to be homogeneous by AFM results and without any cracks and droplets on the surfaces. The present study demonstrates the ability of PLD technique to provide thin films from new stilbazolium dyes with good quality when they are applied as non-linear optical (NLO) organic materials on different type of substrates.
