  1. Photoluminescence properties of hemicyanine dyesin nanosized zeolite pores Doseok Kim, Myounghee Lee, Taekyu Shim Department of Physics, Sogang University Hyunsung Kim, Kyung Byung Yoon Department of Chemistry, Sogang University www.sogang.ac.kr/~nlopt Trebuchet MS, no bold, 32pt center-aligned Trebuchet MS, bold, no italic, 20pt, center-aligned Trebuchet MS, no bold, italic, 16pt, center-aligned

  2. 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

  3. 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

  4. 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

  8. Arial, no bold, 36pt Unit shown after a space Inside a parenthesis Use (arb. Units) when appropriate Line thickness: 1.5 Major tickmarks pointing inward for all sides Legend should be at upper right corner Arial, no bold. 28pt Labels should be (a), (b)… Upper left corner Arial, no bold, 48pt Line thickness: 1.5 Use distinguishable B&W symbols for manuscript, Colors (follow the order suggested by Origin) for PPT Arial, no bold, 28pt Up to ~5 large ticks at most Tickmarks should point into the graph • Based on Origin graph presented in full scale (full ppt presentation, or A4 size) • Origin for your record should have very descriptive title and detailed explanation • including date, sample condition, experimental conditions…
