冷冻和低温（77 ° K）溶液的磷光光谱比荧光光谱具有更多的特征结构和细节。由于激发辐射的散射，它们不包含本底。从而获得更高的分析特异性和灵敏度。有些吲哚衍生物用荧光分光光度法不易区分，但用磷光分光光度法却很容易区分。
Phosphorescence spectra of solutions frozen and at low temperatures (77�K) possess more characteristic structure and detail than fluorescence spectra. They contain no background due to scattering of the exciting radiation. Thus greater analytical specificity and sensitivity are obtained. Some indole derivatives indistinguishable by spectrofluorimetry are easily differentiated by spectrophosphorimetry.
