Abstract:
The study of Nano-semiconductors has a lot of interest due to their optical and electronic properties. In this study, described simple new method was described to prepare silver sulfide nanoparticles (Ag2SNPs). The nanoparticles compounds (NPs) were distinguished by their monocrystalline structure with an effective diameter of 50µm using scanning electron microscope (SEM). Then Energy dispersive X-ray machine (EDX), was used, and showed that there are some impurities in the sample with a concentration of 1%. As for The remaining samples, there are on impurities. As for the Transmission electron microscope (TEM), the spherical particles were the size of an effective diameter 100 nm, and the nanoparticles of the Ag2S were attributed to the surface atomic proportions shown by the sulfide nanoparticles with varying treatment conditions where they appearing the optical and electric properties, where the absorptivity of the samples ranged between (380-450)nm and the absorption coefficient between (2.9-4.9)x〖10〗^3cm and highest energy gaps according to the concentration each sample (1%,3%,5%,7%,9%),(3.31,3.33,3.37,3.42 and 3.47)ev, is Respectively.
