Abstract Nanosized phenyl-capped CdSe particles (quantum dots) were isolated, after preparation inside reversed micelles present in AOT/H2 O/heptane, and then successfully redispersed in amine-functionalized ormosils derived from 3-aminopropyl(trimethoxy)silane (i.e., SA). Doped ormosils were formed into films of a few μm thickness or small bulk samples. Host ormosils were structurally characterized by means of absorption spectroscopy, in the near- and mid-infrared ranges, and by 29Si and 13C solid-state nuclear magnetic resonance (NMR) spectroscopy. Doped ormosils were prepared and investigated via visible spectroscopy. The size of CdSe particles dispersed into the amino-ormosil hosts was calculated using the Effective Mass Model.
