研究了295K和77K下罗丹明B在熔融石英板上吸附的亚单层、单层和多层体系的吸收和荧光性质，推测了295K时罗丹明B的荧光和非荧光二聚体的存在以及低温下聚集体几何结构的变化。讨论了有机晶体上二聚体的非辐射衰变速率和光致电子转移速率及其在空穴注入中的可能作用。
Absorption and fluorescence properties of rhodamine B in submono-, mono-and multilayer systems adsorbed on fused quartz plates have been studied at 295 and 77 K. Existence of fluorescentand nonfluorescent dimers of rhodamine B at 295 K and a structural change of the aggregate geometry at low temperatures have been postulated. Rates of nonradiative decay and photoinduced electron transfer of dimers adsbrbed on organic crystals and their possible role in hole injection are discussed.
