Abstract

The mechanisms of visible light emission of indirect bandgap semiconductor Si and Ge nanocrystals were studied. The nanocrystals were characterized by electron microscopies and steady-state linear optical microscopies. Femtosecond pump-probe spectroscopies on the quantum confined nanocrystals were carried out. Results of the femtosecond hole burning and differential transmission experiments revealed information on the homogeneous lineshape and linewidth of various electronic transitions in the nanocrystals. The origin of the blue and red light emission from these nanocrystals was also addressed.
