We report the rapid high-yield generation of inorganic fullerene-like cesium oxide (IF-Cs2O) nanoparticles, activated by highly concentrated sunlight. The solar process represents an alternative to the only reported method for synthesizing IF-Cs2O nanostructures: laser ablation. IF-Cs2O formed at solar irradiation greater-than or equal to 6W, confirmed by high resolution transmission electron microscopy. These closed-cage Cs2O nanostructures are stable under electron microscope conditions, and also when exposed temporarily to air - of significance for their use in a variety of photonic devices.
