Abstract
The energy transfer in a blend film of poly 3-(2-(5-chlorobenzotriazolo) ethyl) thiophene (PCBET) and polyvinylcarzole (PVK) was investigated. The UV–VIS and photoluminescence (PL) results suggest that the energy transfer from PVK to PCBET leads to the enhancement of PL emission of PCBET. The AFM and LMF results indicated that the domains of blend polymer film are of micro-meter size.
