Abstract
We investigated the preparation and performance of large-area transmission-type flexible plasmonic color filters (PCFs). These large-area PCFs were fabricated based on a nanotransfer printing (nTP) process that involves nanoimprint-based planarization. This process is a simple surface treatment for easy transfer of a metal to a flexible plastic substrate and formation of patterned aluminum nanodots and nanoholes on a substrate surface with poor roughness. Rabbit-ear structures can form during the nTP process, and this phenomenon was analyzed by numerical simulation. As defects were not detected in a 10 000-round bending test, the PCFs fabricated using this nTP process have excellent mechanical properties.
