Influence of different stabilizers on the optical and nonlinear optical properties of CdTe nanoparticles
(2011) In Optics Communications 284(12). p.2900-2904- Abstract
- CdTe semiconductor nanocrystals were synthesized with three different stabilizers: Mercaptoacetic Acid (MM), Mercaptopropionic Acid (MPA) and 2-Mercaptoethanol (ME) at pH approximate to 11.2 by wet chemical route using potassium tellurite and cadmium chloride as starting materials. The effect of capping agent on the preparation of these samples was evaluated using UV-Visible absorption and photoluminescence analysis. With the same reaction time but with different stabilizers, nanocrystals of different diameters were obtained. The average full width at half maximum of the photoluminescence spectra was about 69 nm which indicates that the monodispersity was quite good. The particle size was calculated by Debye-Scherrer equation from XRD... (More)
