| Abstract | ||
| Lead sulfide thin films were deposited by chemical bath deposition onto glass substrates. Depending on the percentage of the constituent bath salts and bath temperature, films with polycrystalline or amorphous structure were obtained. The influence of bath temperature and bath percentage on optical transmittance in the NIR region and structure was investigated. It was found that thickness goes on decreasing as the concentration of lead acetate increases. XRD revealed that the film deposited at 20°C displays no obvious characteristic reflection peaks which could be detected. Large grains are obtained when both deposition time and temperature are increased. | ||
