Welcome to the Single-Particle Spectroscopy Laboratory!

We employ single-particle and ultrafast spectroscopic techniques to investigate the optical properties of various low-dimensional semiconductor nanostructures, with an emphasis on colloidal nanocrystals. Our main purposes are to understand the fundamental optical physics of these low-dimensional semiconductor nanostructures, and to promote their potential applications in optoelectronic devices and quantum information technologies. The research topics we are covering right now include, but are not limited to, single-photon emission, coherent optics, exciton fine structures, resonance fluorescence, two-photon excitation, exciton-phonon coupling, superfluorescence, quantum-confined Stark effect, multiple-exciton generation, energy transfer, phase segregation, and exciton diffusion.
