Antimony tri -sulphide (Sb2S3) thin films are deposited onto glass substrates by vacuum evaporation under the pressure of 2x10-5 Torr. The substrate to source distance is optimized and constant rate of evaporation is maintained. The samples are annealed at 473K and 523K. Similarly by using spray technology three different concentrations of Sb2S3 thin films are prepared by taking different molarities of antimony tri- chloride and thioacetimide by dissolving appropriate amounts of salts in acetic acid. The parameters such as temperature, spray rate and nozzle to substrate distance are optimized and the solution is sprayed onto hot glass substrate. The films obtained by both the methods are further investigated by photo luminescence studies. It is observed that variation of intensity of the luminescence is depending upon the annealing temperature and concentration.

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.
