Abstract

We report the fabrication and characterization of tapered fibers covered with porphyrin monolayer films prepared by Langmuir-Blodgett (LB) deposition method. The studied molecule was 10 mol-% 5,10,15,20- tetrakis(pentafluorophenyl)porphyrin (PFP) entrapped in an octadecylamine (ODA) matrix. PFP molecules, deposited on plane glass surfaces, have relatively long fluorescence lifetime (~ 4 ns) together with high fluorescence efficiency. Therefore, such photoactive materials, example of which are PFP molecules, hold much promise for the development of chemical sensors and efficient light harvesting devices.
