โœฆ Synopsis

Exciton effects are studied theoretically for a quantum well of a semiconductor sandwiched by barriers with a smaller dielectric constant and a larger energy gap. The exciton binding energy increases markedly so that the radiative decay rate of the exciton and the non-linear optical susceptibility are also shown to be enhanced.

The reactions of e,, (CH&COH, and Cd+ with 3 nm CdS particles were investigated by pulse radiolysis. These reactions result in the injection of an excess electron onto the surface of the colloidal particles which leads to a rather drastic bleaching of the absorption of CdS at wavelengths close to th
