荧光产生时间与荧光峰值波长关系的研究

用激光诱导荧光(LIF)方法对芳香族化合物蒽进行了时间分辨谱研究，介绍了所用测试系统的组成和测试方法，获得了蒽的荧光强度-波长-时间三维立体图、峰值荧光时间图、等高图，并对实验结果进行了分析。研究表明，荧光产生的时间与峰值波长有关系，长波早于短波。

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.
