Abstract
Ultra-thin films of amphiphillic squarylium dye were prepared on the hydrophillic substrate by Langmuir-Blodgett(LB) technique. In this study, the photoelectric properties of a amphiphillic squarylium dye LB film was investigated. The visible light(${\lambda}$ = 684nm ) of xenon lamp was illuminated on the amphiphillic squarylium dye LB films and light absorptivity and photoconductivity were observed. The photoconductivity was nearly constant regardless of nominal layer number. The photoelectric properties of the amphiphillic squarylium dye LB films with bottom electrode showed better than that top electrode.
