Strontium doping indium sulfide thin films (In2S3:Sr) were deposited by spray pyrolysis technique on glass substrate at temperature 310C0.The films were prepared by varying the( Sr) ratio from (0.1 , 0.5, 1.5 )% .The effect of Strontium concentration on optical and electrical properties of In2S3:Sr thin films have been studied in detail visible (UV-Vis) transmittance spectroscopy measurements revealed that the optical transmittance of films exceeds 70% in the visible and near infrared region and also the direct band gap energy of the films it decreases with doping Strontium from (2.9ev) to (2.4ev).the mobility and conductivity is increases with doping Strontium and resistivity decreased from (8.5 to 1.74) ᾩcm .
