CdSe quantum dot doped amine-functionalized Ormosils

Nanosized phenyl-capped CdSe particles (quantum dots) were isolated, after preparation inside reversed micelles present in AOT/H2O/heptane, and then s uccessfully redispersed in amine-functionalized Ormosils derived from 3-ami nopropyl(trimethoxy)silane (i.e., SA). Doped ormosils were formed into film s of a few mu m thickness or small bulk samples. Host ormosils were structu rally characterized by means of absorption spectroscopy, in the near- and m id-infrared ranges, and by Si-29 and C-13 solid-state nuclear magnetic reso nance (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.
