Comparison of Growth and Characteristics of PbS Thin Films and PbS Nano Materials

PbS thin films are prepared via chemical bath deposition process at different deposition time. Films are characterized structurally, optically and electrically. PbS nanoparticles and Cu doped PbS nanoparticles are grown by chemical reduction route. These nanoparticles are characterized structurally, optically. The change in band gap with growth time is observed in case of PbS thin films. Doping changes the band gap for PbS nanoparticles.
