Abstract:
Plasmon-enhanced luminescence was developed for luminescent oxygen sensor application. Luminescent polymer Langmuir-Blodgett films containing platinum-porphyrin were assembled plane-to-plane with a silver nanoparticle array. The hybrid polymer nanoassemblies allow more than 10-fold luminescence enhancement in air. The luminescence intensity and lifetime measurements as functions of the number of layers revealed that some platinum-porphyrin, which is close to silver nanoparticles, is effectively enhanced. The enhancement enables us to monitor 2D oxygen distribution mapping on the micrometer scale.
