In this work, extremely fine and pure SnO2 nanoparticles of ~1.1 nm size were synthesized by a solution process, in which amorphous precipitate of SnO2 was crystallized by microwave heating. The particles sizes varied from ~1.1 to ~2.7 nm. By XRD analysis, the particle size, crystal structure and purity of the samples were determined. The UV-Vis measurements of SnO2 nanoparticles, showed that, excitonic peaks existed at ~237, ~250 and ~279 nm corresponding to ~1.1, ~2 and ~2.7 nm clusters respectively. The STM analysis showed that the nanoparticles were spherical in shape, having narrow size distribution.
