Abstract

The method for producing TOPO-coated CdSe NCs was described. The precursors used were dimethyl cadmium and a solution of selenium in tri-n-octyl phosphine (TOP). The precursors were pre-mixed and subsequently introduced in to a reaction flask containing a degassed mixture of TOPO and TOP under a nitrogen atmosphere at an elevated temperature. The surface of the assynthesized CdSe NCs were passivated by a layer of TOPO molecules in the presence of the TOPO/TOP solvent mixture. The composition of the particles was investigated using energy dispersive spectrometry in the TEM. It was found that the Cd₂P ₂Se₆ plates exhibit bend contours in bright field TEM images and were not flat.
