Outline Trebuchet MS, bold, 28pt • Photoluminescence decay lifetime measurement • Our system: Hemicyanine / zeolite (nanoporous system) - Change of PL decay lifetime vs. environment - Forster energy transfer - Determination of hyperpolarizability components of NLO molecule Trebuchet MS, bold, 24pt Trebuchet MS, no bold, 20pt
Photoluminescence from a dye molecule • Absorption of a photon (very fast) • Vibrational relaxation (~ps) • Fluorescence parameters we can study spectrum, quantum yield, lifetime, anisotropy Cy3
Steady state PL & PL decay characteristics low high concentration Use different colors for lines and symbols. Adjust the font size as you resize the graph low high concentration As the dye concentration increases, 1. red-shift of PL peak 2. PL quenching nonradiative relaxation
