This article briefly reviews the author’s recent studies on oxide-based amorphous functional materials, including amorphous and crystalline silica, silsesquioxane-based organic–inorganic hybrids, and the glass-ceramics of sodalites and boracites. The topics covered here are the development and spectroscopic characterization of these materials as well as processes to synthesize them. Major achievements are classified as the exploitation and environmental load reduction of synthesis processes, development and discovery of new materials/substances and phenomena, and evaluation of fundamental properties and values.
