## Abstract The photoluminescence properties of silicon quantum dots may be tailored by surface states via efficient coupling to resonant bulk states. Therefore various wetβchemistry procedures were developed to fabricate silicon quantum dots with adjustable sizes and surface properties. While the
Pentacene microcrystalline thin films have been investigated by pump-probe spectroscopy in the femtosecond regime. The competition between induced absorption in the singlet S, + S, and triplet TI -+ T,, excited electronic configurations and bleaching of the S, + S, transition has been observed. A th
