摘要: In the present work, a combined theoretical and experimental study was performed on structure, optical properties, growth of Ag nanoparticles in metastable β-Ag2WO4 microcrystals. This material synthesized using precipitation method without presence surfactants. The structural behavior analyzed X-ray diffraction Raman infrared spectroscopy. Field-emission scanning electron microscopy revealed irregular spherical-like microcrystals, which were induced by beam irradiation under high vacuum conditions. A detailed analysis optimized geometry results enabled interpretation both spectra provided deeper insight into rationalizing observed morphology. addition, first-principles calculations, within quantum theory atoms molecules framework, an in-depth understanding nucleation early evolution nanoparticles.
