Surface plasmon resonances of metal nanoparticles have shown significant promise for the use of solar energy to drive catalytic chemical reactions. More importantly, understanding and monitoring such catalytic reactions at single‐nanoparticle level is crucial for the study of local reaction processes. Herein, using plasmonic photoluminescence (PL) spectroscopy, we describe a novel sensing method for...
Einzelmolekül‐Fluoreszenzsonde: Über die Bildung der stark fluoreszierenden 4‐NHOH‐Form eines 3,4‐dinitrophenylsubstituierten Bor‐Dipyrromethan‐Farbstoff wird der Elektronentransfer an einzelnen TiO2‐Partikeln untersucht (siehe Bild; B gelb, C grau, F grün, H weiß, O rot). Kinetische und optische Analysen der Fluoreszenzereignisse geben Aufschluss über die Dynamik der molekularen Wechselwirkungen...
