CdSe /ZnTe Core Shell Nanoparticles

Mostly Higher band gap semiconductors have been utilized to coat CdSe ZnTe Core Shell Nanoparticles to form core/shell structures in order to increase their quantum yield. The thin shell layer not only can passivate the dangling bonds and surface defects of quantum dots, thus decreasing the nonradiative pathway, but also can confine carriers, such as holes, more in the core region and away from the surface defects, therefore increasing the possibility of radiative recombination. CdSe ZnTe Core Shell Nanoparticles are biocompatible and water soluble thus can be used for biosensing applications.
