[Studying on the relationship between the fluorescence occurring time and fluorescence summit wavelength]

The authors have detected the fluorescence characteristic of aromatic pollution material-anthracene by OMA and obtained its 3-D(time-wavelength-fluorescence intensity) fluorescence diagrams, three summit wavelengths's fluorescence time spectra, equal high spectra. By analyzing these spectra properties, the authors find that there is a clear order with the occurring time among the three fluorescence summit wavelengths (399 nm, 423 nm, 445 nm). Long fluorescence wave occurs earlier than short fluorescence wave. This solution is also analyzed and explained by atomic energy levels theory.
