Abstract

"In this research work the study of the effect of dopping with Aluminum and Copper by different weights (1,3,5,7)% on the optical properties for (CdS) thin films compound were prepared by chemical spray pyrolysis . Such acompound was deposited on glass slides substrate of (350) nm thickness , such as coefficient of optical absorption which found to be greater than (104) cm-1 for all films , which allowed for electrons transation . Dopping (CdS) thin films by two elements , Aluminum and Copper by different ratios showed small values of energy gap when compared to non-doped thin films . The optical constant such as (absorption coefficient , transmittance) found to be dependent on the dopping ratios of Aluminum and Copper"
