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...

Application of Newton’s Zero Order Caustic for Analysis and Measurement: Part II Fluorescence

Antonio A. Garcia, Luis Nuñez, Carissa Henricksen & Vladimiro Mujica · International Research Journal of Pure and Applied Chemistry · 2013

An oblate spheroid-shaped liquid solution acts as a lens through the phenomenon of Newton’s zero order caustic resulting in the focusing of a low power source into high intensity light within the sample to detect and measure fluorescence. Microwatt LED sources can be used to meas...
