本文研究了罗丹明B在熔融石英表面亚单层、单层和多层体系中的吸收和荧光性质。存在的荧光和非荧光二聚体的罗丹明B在295 K和结构变化的聚集体的几何形状在低温下已被假定。本文讨论了吸附在有机晶体上的二聚体的非辐射衰减和光诱导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.
