In this paper we obtained thin films of As2S3 by chemical bath deposition. The films were prepared at a temperature of 80 ºC for 3 hours each deposit. They were thermally treated at 180 ºC and 250 ºC for 30 minutes for 1 hour, respectively. The energy gap was calculated 2.9 eV. The conductivity was around, 3.62X10-1 (O*cmr'.
