Description
Summary:Different concepts for the functionalization of inorganic semiconductors are investigated. These include functionalization by gallium nitride based nanowires as well as functionalization by organotetrel cluster-molecules. The nanowires are investigated by time-resolved photoluminescence and external quantum efficiency measurements. The cluster-molecules are investigated in regards to their stability and nonlinear optical properties. Ultimately a cluster-molecule with an ultra-low threshold is found that provides supercontinuum generation using a continous-wave laser diode. For a better understaning of the white-light generating process, nummerical simulations based on a semi-classical model are performed.
