Phenyl-capped CdSe nanometre sized particles (quantum dots) were isolated after preparation inside reversed micelles present in AOT/H2O/heptane and then successfully redispersed in aminosilicate ormosils derived from either 3-aminopropyl(trimethoxy)silane (i.e. SA) or N-[3-trimethoxy]silyl(propyl)ethylene-diamine (i.e. DA). Doped ormosils were formed into films of a few um thickness or small bulk samples. Host ormosils were structurally characterised by means of absorption spectroscopy, inthe near and mid infrared ranges and by 29Si and 13C solid state nuclear magnetic resonance (NMR) spectroscopy.
