| Research Abstract |
Fabrication by laser ablation and optical manipulation of quantum dots of wide-gap semiconductor CuCl and ZnO under the resonant excitation condition have been successfully performed in superfluid helium, which provides an ideal free space for the optical manipulation with low temperature, negligible viscosity, high thermal conductivity, chemical inactivity, and wide optical transparency. We firstly demonstrated the size-selective manipulation of the quantum dots.
