Preparation and optical properties of CdSe/polymer nanocomposites

It is shown that tri-n-octylphosphine oxide (TOPO)-capped nanocrystals prepared by the single source approach may be successfully used as starting materials to produce inorganic /polymer nanocomposites. The CdSe/polymer composites still show optical properties that are associated with quantum size e...

Description
Summary:It is shown that tri-n-octylphosphine oxide (TOPO)-capped nanocrystals prepared by the single source approach may be successfully used as starting materials to produce inorganic /polymer nanocomposites. The CdSe/polymer composites still show optical properties that are associated with quantum size effects intrinsic to the CdSe nanocrystals used. It is inferred that the preparation of a wide range of novel nanocomposites is possible once the particles surface becomes compatible with the polymer matrix by using a convenient capping agent, such as TOPO, during the synthetic process.
