Abstract
Lead chromate nanoparticles were synthesized via chemical co-precipitation method from lead chloride and potassium chromate. The formed nanoparticle is characterized by powder x-ray diffraction, scanning electron microscopy, ultra-violet spectroscopy and fourier transform infrared spectroscopy, confirmed the preferential growth of lead chro- mate nanoparticles that width is 70.423nm. The SEM image shows the synthesized lead chromate show well crystallized particles with tetrahedral morphology. The FTIR spectrum is used to study the stretching and bending frequencies of molecular functional groups in the sample. From UV spectrum, the band gap of lead chromate nanoparticles is found to be 4.4eV.
