✦ Synopsis

Multiple quantum well structures consisting of alternating layers of two crystaUine organic semiconductors PTCDA and NTCDA are considered. It is shown that the bluesbift of the lowest energy PTCDA singlet exciton line with decreasing layer thickness is described quantitively within the model of "small radius" excitons.

A theory is presented for electromagnetic energy transfer and absorption mediated by quasi-twodimensional excitons in regular multiple-quantum-well (MQW) structures. The absorptivity, absorption coefficient and their integrals over the photon frequency are generally expressed as functions of the rat
