摘要
The properties of materials drastically change when matter performs a transition from bulk to nano size. The quantum dots (QDs) of lead sulphide (PbS) embedded into Polyvinyl alcohol (PVA) are synthesized via one pot synthesis chemical method. The specimen has been analyzed by UV/VIS absorption spectroscopy, High resolution transmission electron microscopy (HRTEM) and fluorescence spectroscopy. Quantum Dot size is calculated from the absorption spectra using hyperbolic band model and sizes of the dots are found to be around 6nm and the calculated value is in agreement with the size as determined by HRTEM. The photoluminescence spectra was also obtained for the samples.
