Photolumnescent of plasma polymerim benzene

Summary form only given. The photoluminescent properties of plasma benezen films are investigated. The photoluminescence is a fluoresconce rather than a process with a lifetime on the order of a few nanoseconds. Picosecond(ps) photoluminescence of samples indicated that the decay is a tri-exponential, with lifetime 0.4ns, 1.2ns and 2.3ns with excited by 532 nm laser. Again, the fluorescence is not produced by a few distinct chromophores , or is produced by different process such an excition complex or a band transition.
