Effect of Growth Temperature on Chemical Synthesis of PbS quantum dots

P. K. Kalita, B. Das & R. Devi · International Research Journal of Pure and Applied Chemistry · 2013

PbS quantum dots synthesized at room temperature through CBD technique show a large blue shift of absorption edge due to formation of very small particle size of the order of 2nm confirmed by HRTEM measurement. It exhibits a further blue shift when synthesized in acidic medium (p...
