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.
等离子体增强发光被开发用于荧光氧传感器应用。含有铂卟啉的荧光聚合物 Langmuir-Blodgett 膜通过银纳米粒子阵列进行面-面组装。这种混合聚合物纳米组装体在空气中的发光增强超过 10 倍。发光强度和寿命随层数的变化测量表明，靠近银纳米粒子的一些铂卟啉被有效增强。这种增强使我们能够监测到微米尺度上的二维氧分布映射。
