用常规的荧光光谱仪有时难以得到分辨率足够高的光谱,其选择性和灵敏度常常满足不了实际工作的需要。因此人们发展了诸如基于低温Shpolskii效应的荧光窄线光谱法、用激光作光源的激光荧光光谱法、利用不同物质有不同蒸发温度的蒸汽相荧光光谱法等新型的荧光光谱技术,以消除分子间的相互作用和其它因素的影响,提高光谱的分 With conventional fluorescence spectrometers, it is sometimes difficult to obtain spectra of sufficiently high resolution, and their selectivity and sensitivity often can not meet the needs of practical work. Therefore, people have developed new fluorescence spectroscopy methods such as narrow-line fluorescence spectroscopy based on the low-temperature Shpolskii effect, laser fluorescence spectroscopy using a laser as a light source, and vapor-phase fluorescence spectroscopy using different vaporization temperatures of different substances to eliminate intermolecular The interaction and other factors that affect the spectral fraction increase
