- Abstract
- Thin films of the blend luminescent poly 3-(2-(5-chlorobenzotriazolo)ethyl) thiophene (PCBET) with poly-(p-(methyl)-phenylmethacrylate) (PMPMA), polyvinylcarzole (PVK), and poly (methyl methacrylate) (PMMA) were deposited by spin coating. Systematic studies on optical properties, the concentration effect, and energy transfer of these conjugated polymers within the blend films are discussed. Fluorescence lifetimes of excited state in the blend films were investigated by nanosecond time-resolved spectroscopy, UV-vis, photoluminescence (PL), synchronous PL spectra. These results and analysis suggest that energy transfer, from good matrix material (PMPMA and PVK) with active chromophores to PCBET, leads to the enhancement of PL emission of PCBET in a blend system.
