摘要
Lead iodide, bromide and chloride nanoparticles (NP-PbX2, X = I, Br and Cl) with various morphologies were successfully prepared through a simple hydrothermal method without any additives or stabilizers. By treating the PbX2 in EtOH/CH2Cl2 solution at 170 degrees C for 12 h, the corresponding PbX2 nanoparticles were synthesized. The average sizes of PbX2 nanoparticles were between 30 and 80 nm. The structure, morphology, surface and size of PbX2 nanoparticles were determined by X-ray diffraction powder, Scanning Electron Microscopy, solid state Photo Luminescent, BET surface area and solid state UV.
