| 摘 要： | 用Nd:YAG的二倍频532 nm激光对几种不同水体的激光诱导荧光(LIF)光谱进行了测量,利用特征光谱荧光标记(SFS)技术指认出水体中溶解有机物(DOM)、叶绿素a(Chl a)及类胡萝卜素等物质的特征光谱带.指出在455 nm波长处具有较大强度的荧光峰是附属色素中抗氧化作用的类胡萝卜素(PPC)的贡献.提出了激光诱导PPC荧光频率上转换发射的动力学模型.

| Abstract: | The fluorescence spectra of several types of water samples in combination with laser-induced fluorescence(LIF) measurements using 532 nm wavelength excitation source were measured in the laboratory,and the fluorescence matters such as dissolved organic matter(DOM),chlorophyll a(Chl a) and carotenoids were pointed out with spectral fluorescent signature(SFS) technique.It is considered that the peak at 455 nm in the spectrum is contributed by carotenoid(PPC).Finally,the dynamic model of PPC's fluorescence emission is showed. |
