    A simple, inexpensive, and reproducible photothermal procedure for synthesizing IF-Cs2O nanoparticles with immensely concentrated sunlight was demonstrated. The solar-driven synthesis of IF-Cs2O was performed in evacuated quartz ampoules that contained 3R-Cs2-O crystallites under continuous irradiation with a concentrated solar power of 2.0-7.7 W, and periods ranging from 30 to 840 s. Samples were collected from the deposit that gathered on the quartz ampoule during the solar irradiation for TEM analysis. The interaction of the beam with the materials led to thermal motion, charging, desorption of trace quantities, or possible chemical changes. The results of the electron energy loss spectroscopy and imaging with a Gatan imaging filters proved that only cesium and oxygen were present in the nanoparticles.
