Abstract

Metal-enhanced multiphoton absorption polymerization (MEMAP) is studied using gold nanowires with a set of three different photoresists. Photoresists that employ radical and cationic polymerization are investigated. In all cases, MEMAP is strongly correlated with multiphoton-absorption-induced luminescence (MAIL) of the nanowires. Wavelength-dependent studies indicate that the dominant mechanism for MEMAP is not field-enhanced two-photon absorption of the photoinitiator, but rather single-photon excitation of the photoinitiator by the broadband MAIL emission.
