| Popis: | Stable monolayers of Tb (III) -ocat-4-n-nonyloxyphthalocyanine (TbPc2) and TbPc2 blended with amphibious arachidic acid (AA) on air-water interface have been obtained and their solid multilayers have been successfully deposited by Langmuir-Blodgett (LB) technique. The characteristics of their structure and fluorescence are disclosed. The multilayer has a periodic layered structure with a layer spacing of 2.2 nm. Fluorescence lifetime results suggest that the excitons exist by photo-excitation in the film of TbPc2. |
