Zinc Bismuth Sulfide (ZnBi2S3) thin films are successfully deposited on a glass substrate by chemical bath deposition technique at different bath temperatures (60°C, 70°C, 80°C). The basic chemical bath contains bismuth nitrate, zinc nitrate and sodium thiosulphate as chemical reagents. The deposited films are characterized by XRD, FESEM, EDAX, UV Spectroscopy and PL for structural, morphological and optical properties. The formation of ZnBi2S3 is evidenced by the peaks in X-ray diffraction pattern. FESEM observation indicates the spherical grain shape of films at different temperatures. EDAX confirms the composition of ZnBi2S3. The bandgap energy obtained for deposited films is in the order of 2.31eV and depends on the film thickness. The PL spectrum reveals the green emission in the visible region.The Present work indicates the feasibility of ZnBi2S3 as a solar material..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
