摘要：

Application of a solar-driven synthesis approach for the production of fullerene-like Cs2O nanoparticles is presented (see figure). The synthesis is performed directly in evacuated quartz ampoules containing a Cs2O crystallite precursor under continuous irradiation with highly concentrated sunlight. Closed-cage nested Cs2O structures are obtained in a variety of shapes and dimensions. These structures are rather stable, a significant advantage for photoemissive applications involving Cs2O coatings.
