I am Li Guo from China. I got my B.S degree in Peking University in China. Now I am working on my Ph.D degree. My research interest is in the application of semiconductor nanocrystals. Nanocrystals exhibit size-dependent electronic and optical properties, which make them attractive candidates for use in a wide range of optoelectronic devices where the absorption or emission may be tuned through control of the nanocrystal size, such as lasers. The nanocrystal emission spectrum can be modified not only by control of the particle size, but also by changing the optical environment in which the particles are situated, such as in the microcavities.
