Description
Summary:The polyethylene glycol (PEG) capped lead sulphide (PbS) nanoparticles were successfully synthesized by simple wet chemical method. The synthesized product has been characterized by powder X-ray diffraction (XRD), UV–vis spectrophotometry, FTIR spectroscopy, transmission electron microscopy and photoluminescence studies. The size of the PEG capped PbS nanoparticles was determined from XRD and it is found that the size of the particles of the order of 43–4 nm. Significant “blue shift” from bulk material was observed on the PbS nanoparticles using UV–Vis and photoluminescence spectrum. A eightfold increase in photoluminescence intensity is reached at 6 g PEG addition.
