High Resolution TEM Analysis of CuInS2 Nanoparticles and XRD analysis of CuInS2 Thin Films
EMSL Project ID
17795
Abstract
The groups of Pak and Rodriguez have accomplished the first microwave-assisted preparation of chalocopyrite nanoparticles from single source precursors (SSPs) containing stoichiometric amount of Cu, In and S. Particularly, colloidal CuInS2 nanocrystals have been produced by microwave-assisted decomposition of the SSPs in the presence of alkykthiol ligands in dioctyl phthalate as a solvent. They observed nanoparticle formation at temperatures as low as 125?C with 5 minutes of microwave irradiation. Unlike the thin film preparation, several SSPs derivatives produce only chalcopyrite phase. Using this technology, they were able to prepare CuInS2 nanoparticles at lower reaction temperatures and in shorter reaction time than by conventional thermolysis techniques. In addition, they are starting to show that good control over the size of nanoparticles can be achieved by optimizing the reaction parameters. The resulting nanoparticles exhibit expected properties such as room-temperature fluorescence. In additon, CuInS2 thin films have been prepared using SSP via radiao frequency induced plasma chemical deposition
