Abstract: This is a novel project since no previous work in stabilization of VO2 nanocrystals in suspension has beenperformed. In this project, VO2 (M) nanocrystals are synthesized in a one-step microwave assisted technique. It is an efficient method since no post annealing processes are needed. Moreover, vanadyl acetylacetonate is the only precursor toform the adequate nanocrystals. The crystallinity, size and surface were characterized by X-ray diffraction (XRD), dynamic light scattering (DLS), infrared (IR), transmission electron microscopy (TEM) and nuclear magnetic resonance (NMR). The nanocrystals are stabilized by a combination of oleylamine and oleic acid as surfactants. This results in stable and monodisperse VO2 (M) elongated nanocrystals suspended in chloroform. This work is a first step towards a DSD experiment to optimize the synthesis parameters in order to prepare high quality and size appropiate VO2 (M) nanocrystals for smart windows.
