Synthesis, Characterization and Photophysical Analysis of CDS Nanoparticles

Abstract

The CdS quantum dots are prepared in AOT reverse micellar self-assemblies. The quantum dots were prepared from different precursor ratios of 1:1 and 1:2 which yielded different particle size. Steady state luminescence quenching studies were carried out for these quantum dots with N, N-dimethyl amine and triethyl amine. The downward curvature was observed form the SternVolmer plots showing the static nature of the quenching process. The static nature is attributed to presence of the quencher molecules to the quantum dot surface.
