Effect of pH of Synthesis on CdS/L-cys Colloidal Solutions Optical Properties
Journal Title: Фізика і хімія твердого тіла - Year 2016, Vol 17, Issue 1
Abstract
The purpose of this paper is to summarize experimental data of CdS/L-cystein nanoparticles (NPs) colloid solutions optical properties as function of 3-component mixture (Cd2+ – S2- – L-cys) content and pH. The NPs synthesis was carried out at pH=7, 9 and 11 in the wide composition range based on literature data. The influence of the solutions composition on the colloids stability and the CdS/L-cys NPs size was monitored by absorption and fluorescence spectra observation at room temperature and studied by TEM. A polynomial model was used for the responses produced from Scheffe’s simplex lattice design with fourth degree terms. Keywords: nanoparticles, CdS/L-cystein, absorption spectra, photo luminescence, quantum yield, mathematic experiments planning, simplex-lattice analyses.
