Abstract

Thermal evaporation technique has been employed to grow silver phthalocyanine nanostructures on glass substrates kept at different substrate temperature in vacuum of 10−5 Torr. These samples have been studied for their structural and optical properties. TEM investigations show the formation of long nanowires in AgPc thin films prepared at substrate temperature of 298 and 303 K, whereas films prepared at 308 K show the formation of nanobelts. XRD observations reveal that silver phthalocyanine nanowires are crystalline in nature. The significant blue shift in the UV-VIS absorption spectra of the silver phthalocyanine nanowires in comparison to bulk sample, indicate of effect of quantum confinement.
