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.
