Dyes change their absorption curve when exposed to an electric field. The conditions under which this effect can be made large enough for application to light modulation are discussed. Theoretical expectations correspond with recorded curves of a tes

The dependence of space charge influenced current transients on the spatial distribution of photogenerated carriers in the bulk of a conductivity cell was investigated with the aim of correlating the observed time evolution of the currents with carri

The photoconductivity signal consecutive to a light pulse from a 337.1 nm N2 laser can be understood as the superposition of photocurrents stremming from two distinct photoionization mechanisms. Low light intensity (5 × 1021 quanta/cm2s) favors the

The question under what conditions a molecule passes at an avoided crossing from the upper electronic state to the lower is discussed in the Born-Oppenheimer approximation. This avoids the introduction of the velocity which occurs in the usual Landau

The calculations are based on the following model: Triplet pair states are formed by diffusion controlled encounters of molecules in the triple state. The pair state is characterized by JQ, the energetic splitting of its singlet and quintet component

A short survey is given on the mechanisms by which dye molecules may convert the absorbed radiation energy into chemical energy, electrical energy, or heat. The importance of the different processes in the utilization of solar energy and their influe

On the Luminescence of 9-Fluorenone The fluorescence of 9-fluorenone has been measured in various solvents. At room temperature and for non-hydrogen bonding solvents an emission with 19.3 ⩽ max ⩽ 21.4 · 103 cm−1 is found, whereas the fluoresce
