Optimization of Laser-Induced Breakdown Spectroscopy (LIBS) for Determination of Quantum Dots (Qds) in Liquid Solutions

Year: 2012 Volume: 6 Issue: 12 1762 - 1765 Pages

Abstract: Here we report on the utilization of Laser-Induced Breakdown Spectroscopy (LIBS) for determination of Quantum Dots (QDs) in liquid solution. The process of optimization of experimental conditions from choosing the carrier medium to application of colloid QDs is described. The main goal was to get the best possible signal to noise ratio. The results obtained from the measurements confirmed the capability of LIBS technique for qualitative and afterwards quantitative determination of QDs in liquid solution.
