Fig. 9(Color online) The excitation spectrum of bis-MSB calculated with a density functional theory-based code and the measured excitation spectrum of LAB+PPO+bis-MSB. Compared to
, the absence of the excitation spectrum near 320 nm for LAB and the difference in intensity between the spectrum near 355 nm for PPO and the spectrum near 400 nm for bis-MSB suggest that effective resonance energy transfer has occurred.
