Abstract
Stable monolayers of Tb (III) -ocat-4-n-nonyloxyphthalocyanine (TbPc 2) and TbPc 2 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 TbPc 2. © (2011) Trans Tech Publications, Switzerland.
