Abstract

Control over spatial positioning of CdSe quantum dots(QDs) is a very important criterion for device fabrication. These authors utilize the ordered array of pores provided by the mesoporous material MCM-41 to achieve this. TEM of a single CdSe@MCM-41 particle (see Figure) shows that the hexagonally ordered mesostructure of MCM-41 is still intact after the growth of CdSe nanoparticles inside the mesopores.
