摘要：

Phase spectra are used to improve the resolution of the chronospectroscopic method for luminescence studies. From the analysis of these phase spectra the range is found for which the separation power is maximum. The phase difference Delta phi between two luminescent lines is calculated, using a simple three-level fluorescence system, as a function of the modulation frequency omega of the excitation light. The well-resolved spectrum of U6+ in NaF obtained by suppressing the 555.0 nm line at 1010 Hz modulation frequency is also presented.
