Abstract
Monoclinic tungsten trioxide (WO3) thin films have been successfully synthesized on the glass substrate in a reactive environment (Ar/O2) using DC magnetron sputtering. Effect of substrate temperature (RT–450°C) on wetting and other physical properties of the films was investigated comprehensively. Various standard techniques, such as XRD, XPS and FESEM were employed to examine the physical properties of deposited films, while the sessile drop method-based contact angle measurement was employed to examine the wetting properties. The important findings of our study demonstrated the significant role played by the substrate temperature in enhancing the film properties. The WO3 thin film synthesized at 450°C shows the preferred (020) orientation with a large crystallite size of about 68.2 nm. Further, this film showed high porosity and displayed a hydrophobic nature comparable to others, which makes it highly suitable for applications in sensing and water-repellent fields.
期刊介绍:
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
