This activity leads students through the synthesis of compound nanoparticles and examines how key physical properties such as band gap vary with particle size. Prior to doing this, students should have some exposure to the structure of solids, band theory, and band gap as a periodic property (see, for example, Lisensky, et al. J Chem.
In this lab experiment, students use sol-gel chemistry to prepare silica gel monoliths from tetraethylorthosilicate (TEOS). Carrying out the hydrolysis and condensation under acid-catalyzed vs.
