Abstract :

Photoluminescence analysis is a useful method to study the optical properties of semiconductor nanostructures. Distinct processes take place to result in the light emission from the nanostructure. Various deposition methods and morphologies changed the emission band in semiconductor nanostructures. Three different morphology of Lead Sulfide structures such as nonospheres, star-shaped and dendrite nanostructures have been analyzed and the Photoluminescence results were compared. In three cases, band emissions are in visible region and it was observed that the incidence of quantum limits in resulting of increasing surface to volume ratio is impressive to optical properties.
