Excimer laser- (248 nm) induced pyrene implantation in a solid polymer has been investigated in the forward-transfer configuration. Atomic force microscopy provides detailed topological images of the implanted surface, the geometry of which remains mostly unaltered following low-intensity laser radiation in contrast to a laser ablation transfer case. The dopant host polymer thickness appears to strongly influence the efficiency of the process. The experimental results are interpreted on the basis of a thermally activated ejection and implantation mechanism.
