Thermal stability and optical property of ormocers (organically modified ceramics) nanoparticles produced from copolymerization between amino-silanes and tetraethoxysilane

► Withstanding of aminopropyl located inside the silica network at high temperature ► Loss of organic species only from the surface of organo-modified silica ► Decrease in band intensity and band shift with increase in heating temperature ► UV bands resulting from the existence of oxygen-related defect
