Rezumat:

In situ organically-modified silsesquioxane nanoparticles with vinyl units were obtained combining the sol-gel technique and the radical polymerization of vinyltrimethoxysilane (VTMS) in the presence of a small amount of a cationic surfactant, i.e., cetyl trimethylammonium bromide (CTAB). The surfactant was added in order to improve the optical properties based on controlled nanophase separations. The hydrolysis and polycondensation reactions were followed by Fourier Transform infrared spectrometry (FTIR), Scanning electron microscopy (SEM) and fluorescence measurements.
