Homogeneous coating of photonic macroporous oxides with inorganic nanocrystals

摘要

A simple method to obtain homogeneous sub-monolayer coverage of metal oxide and chalcogenide nanocrystals onto porous oxide supports is described. Quantitative nanoparticle coverage was probed using photonic macroporous oxide supports. Composites of nanocrystals of TiO2 Fe3O4 or CdS dispersed onto macroporous SiO2 or ZrO2 all show a predictable linear shift in the photonic stop band position.
