Synthesis of PbI2 nanoparticles by laser ablation in methanol

We report the first synthesis of colloidal lead iodide PbI 2 nanoparticles by pulsed laser ablation in methanol. Structural and optical properties of PbI 2 nanoparticles were investigated. The optical absorption data showed three distinct absorption peaks (Plasmon) at 220, 250 and 302 nm, with a dir...

Description
Summary:We report the first synthesis of colloidal lead iodide PbI 2 nanoparticles by pulsed laser ablation in methanol. Structural and optical properties of PbI 2 nanoparticles were investigated. The optical absorption data showed three distinct absorption peaks (Plasmon) at 220, 250 and 302 nm, with a direct optical band gap of 2.82 eV. X-ray diffraction XRD analysis revealed that the synthesized PbI 2 nanoparticles were polycrystalline in nature with hexagonal phase. Transmission electron microscope (TEM) investigation displayed (18–40 nm) spherical PbI 2 nanoparticles. The electrical and photo-response characteristics of PbI 2 nanoparticles/n-Si heterojunction were measured and analyzed.
