Abstract

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. The structural properties of the nanocrystals (NCs) were analyzed using high resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SAED) and X-ray diffraction (XRD). The composition was verified using X-ray photoelectron spectroscopy (XPS), inductive coupled plasma-optical emission spectroscopy (ICP-OES) and energy dispersive X-ray spectroscopy (EDX). The optical studies were performed using UV-VIS-NIR spectroscopy and photoluminescence (PL) spectroscopy and the band gap value obtained was verified using cyclic voltammetry (CV). The nanostructures grown were spherical with a size of about 5 nm possessing appreciable monodispersity.
