CuZnInTe quantum dots-a novel nanostructure employing a green synthesis route.

We report the synthesis and characterisation of novel CuZnInTe quantum dots (QDs) suitable for various optoelectronic applications. The nanostructures grown are technologically important due to their Cd and Pb-free composition. The synthesis was maintained "green" by using a phosphine free organometallic procedure utilizing octadecene as the coordinating solvent.

CuInS-InSe quantum dots - a novel material a green synthesis approach.

Novel CuInS-InSe QDs were prepared by a two stage organometallic colloidal synthesis procedure. A layer of indium selenide was grown over the CuInS QD core, under high temperature in the presence of oleylamine. The optical properties of the nanostructures grown were studied using UV-Vis absorption spectroscopy and the band gap obtained was in line with the cyclic voltammetry (CV) results.
