Abstract

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 .
