Structural and Optical Properties of Nanocrystalline Pbs Thin Films Prepared by Microwave-Assisted Chemical Bath Deposition
Nanocrystalline lead sulfide (PbS) thin films have been successfully deposited onto glass substrate via microwave assisted chemical bath deposition. Aqueous solutions of lead nitrate Pb(NO3) and thiourea [SC(NH2)2] were used as lead and sulfur ion sources respectively. Structural and morphological s...

| description | Nanocrystalline lead sulfide (PbS) thin films have been successfully deposited onto glass substrate via microwave assisted chemical bath deposition. Aqueous solutions of lead nitrate Pb(NO3) and thiourea [SC(NH2)2] were used as lead and sulfur ion sources respectively. Structural and morphological studies revealed a high synthesized nanocrystalline PbS thin films quality. Optical studies showed a significant blue shifting in the energy gap of the prepared nanocrystalline PbS thin films. Compared with bulk PbS, the prepared nanocrystalline PbS showed large energy gap, value of about 2.4 eV. This could be attributed to the confinement effect of nanocrystalline PbS thin films. The study introduced a simple and cost-effective method to further investigate other properties of nanocrystalline PbS thin films such as electrical and morphological properties. |
