Abstract

•Cadmium sulphide (CdS) emerged as one of the important semiconducting materials.•A simple CBD technique for the preparation of CdS nanostructured crystalline thin films.•Surface morphology of these films has been modified by varying complexing agent.•Nano-seaweed-coral and honeycomb structure like CdS thin films are achieved for the first time.•Also honeycomb-like-nanostructured thin film nano-walls are achieved for the first time.

Nanostructures of cadmium sulphide (CdS) have been attracting considerable research interests in electronic device fabrication due to their unique wide band gap (~2.4 eV) and high photosensitivity. Thin-films of CdS nanostructure have huge potential for solar cells, flat-panel displays and light-emitting-diodes. However, lack of a simple and convenient preparation method impedes their wide-spread device development. Here, a facile, efficient and scalable chemical bath deposition technique based preparation of thin films of CdS nanostructure is reported. Utilization of various complexing agents in the reaction mixture provided a unique surface topography to the CdS nanostructures similar to biological objects such as seaweed, coral-reef, and honeycomb. For the first time nanocrystalline, optical absorbance and morphology of three different CdS nanostructures derived from CBD are discussed.
