Effect of added Co on the laser ablation of 3,4,9,10-perylene tetracarboxylic dianhydride

Addition of Co to the target material was found to be very effective on the lowering of processing temperature (208C instead of 3008C) in the excimer laser ablation (ELA) at 308 nm of a solid monomer target of 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA) for the preparation of a thin ®lm of a polymer with the polyperinaphthalene (PPN) structure on a temperature-controlled substrate. # 2000 Elsevier Science B.V.
