The II-VI group compounds (CdSe, ZnSe, CdS, CdTe etc.) are important because of their photovoltaic, photoelectrochemical (PEC) and electroluminescent applications and have received much attention [1–3]. Recently there have been many efforts to produce nano-sized materials, because the electrical and optical properties can be varied via chemical control over size, stoichiometry and interparticle separation [4–7]. These materials have been synthesized by various techniques including pyrolysis of organometallic compounds. Sol-gel synthesis, chemical bath deposition, electrodeposition etc. [8, 9]. CdSe films have earlier been electrodeposited on gold coated glass substrates at 120 ◦C by dissolving the precursors in DMSO [9]. In the present work, CdSe films were deposited by pulse electrodeposition with and without sonication. Earlier there was a report [10] on the synthesis of CdSe powder by a combination of pulse plating and pulsed sonication, where the titanium substrate itselfwas pulse sonicated which prevented the growth of films; the films formed during a pulse were removed from the titanium substrate and the powder collected at the bottom. In this work, CdSe films were pulse plated at different duty cycles in the presence and absence of ultrasonic field.
