Abstract :Saccharin which so-called as benzoic sulfimide is an artificial sweetener. In this paper, nanostructured lead sulfide insert ignore into journalissuearticles values(PbS); thin films were produced in the presence of additive known as saccharin via chemical bath deposition insert ignore into journalissuearticles values(CBD);. Effect of the saccharin content on the morphological, optical and structural properties of the films has been investigated. Lead sulfide insert ignore into journalissuearticles values(PbS); films that included additive were prepared at five different concentrations of saccharin insert ignore into journalissuearticles values(from 0 to 5%);. The fabricated samples were characterized by surface roughness, scanning electron microscopy insert ignore into journalissuearticles values(SEM);, X-Ray diffraction and UV-vis spectroscopy. It was found that the presence of saccharin highly affected the optical and structural properties of PbS thin films. According to the X-Ray diffraction results, crystallite size values of the films decreased from 12.88 to 5.25 nm with increasing of saccharin content. UV-vis measurements showed that both the band gap and transmission properties of the films increased as a result of increasing saccharin concentration. Further, Surface roughness measurements exhibited that average surface roughness was diminished with increasing saccharin content. As a result, it has been found that the presence of saccharin in growth solution played a significant mission in adjusting the main physical properties of the samples.
