Abstract: A polymer, poly(phenylcarbyne) (PPC), was converted to carbon film by ultraviolet pulsed-laser (KrF, λ = 248 nm) irradiation in nitrogen atmosphere at room temperature. The irradiated PPC consisted of fine graphitic carbon particles of several tens of nm in size, and exhibited good field emission properties. Low turn-on emission field of 2 V/μm (at 1 nA/cm2), high emission current density of 20 mA/cm2 (at 12 V/μm), and high emission luminescent spots density of 104/cm2 were observed for the polymer film irradiated by a pulsed-laser fluence of 40 mJ/cm2. We demonstrate multiple-lines and 2×5 array field emission patterns using the laser irradiation of PPC. © 2001 American Institute of Physics.
