SnO₂ nanocrystals (NCs) are industrially important, n-type metal oxide materials with a range of potential applications including transparent conductive electrodes, photovoltaic devices, gas sensors, and detection of metal ions. Such applications require SnO₂ NCs with a specific morphology. Therefore, it is important to investigate parameters influencing these morphologies. In this work, the influence of water and 2-propanol on the morphology of SnO₂ NCs synthesized by the microwave method has been studied. Results show a varying SnO₂ NCs were obtained as the compositions of water and 2-propanol were varied during the microwave synthesis. The SnO₂ were characterized by TEM, SEM, XRD, Raman and PL.
