Fabrication of Luminescent Superparamagnetic CdSe-QDs/SiO2/Fe3O4 nanocomposite particles

Liu B., Wang D., Huang W., Xie W., Yu M., Yao A., Tongji University, CN

A new kind of water-soluble luminescent superparamagnetic nanocomposite particles has been synthesized using a modified Stöber method combined with an electrostatic assembly process. Fe3O4 nanoparticles with the size of 10 nm were uniformly coated with [...]

Transition of the Ground State in a Coupled N-layer Quantum Dot

Xie W., Guangzhou University, CN

There has been growing interest in the physics of quantum dots (QDs) in recent years because of the rapid development of fabrication technology. Most theoretical and experimental studies have been so far focused on the [...]

Binding Energy of an Exciton Bound to a Charged Impurity in Quantum Dots

Xie W., Guangzhou University, CN

Binding energies for an exciton (X) trapped in the two-dimensional quantum dot by a charged impurity located on the z axis at a distance from the dot plane are calculated using the method of few-body [...]
