Abstract
248-nm laser ablation of poly(methyl methacrylate) plates and soaking of the ablated plates in aqueous solution of rhodamine B resulted in fluorescent micropattern formation. A positive or negative fluorescent pattern of the dye was obtained by controlling the laser fluence. Incorporation mechanism of the dye into the ablated polymer is discussed.
