The paper describes the photoelectrochemical studies and the electrochemical synthesis of zinc selenide thin films. Obtained results specify the range of potentials where semiconducting compound is deposited. Photocurrent profiles indicate the p-type conductivity of the electrodeposited semiconductor. The generated photocurrent indicates the anomalous absorption of the light below the band gap range of ZnSe and suggests a plasmon-exciton coupling effect. (C) 2012 Elsevier B.V. All rights reserved.
