Synthesis of Non-Spherical CdSe Quantum Dots

Keywords: , , ,

Here we describe the synthesis of non-spherical CdSe quantum dots (QDs) through high temperature reduction in the presence of TOP (Tri-n-octylphosphine) and TOPO (Tri-n-octylphosphine oxide). High affinity of phosphine oxide to the surface of CdSe nanocrystals usually leads to formation of spherical particles with diameter between 1.5 and 10 nanometers.1 However, the addition of Carbon Nanohorns (CNHs) into the reaction mixture led to formation of different shapes of nanocrystals.
