摘要：

The Langmuir-Blodgett (LB) technique is used to deposit monolayers of nearly monodisperse nanometer-size CdSe crystallites (quantum dots) onto various substrates. Size-selected CdSe nanocrystallites capped with trioctylphosphine oxide are directly applied onto the water surface of a LB trough and serve as the LB-active species. Absorption and luminescence studies of monolayers transferred onto glass slides indicate that the monolayers retain the general optical properties of isolated crystallites. Transmission electron micrographs of monolayers on amorphous carbon show the formation of two-dimensional hexagonal close-packed domains.
