Time-resolved multispectral luminescence method for analysis of minerals

We have developed a procedure for time-resolved luminescence analysis with excitation of samples by a nanosecond electron beam and recording the luminescence decay kinetics in four spectral bands. Using as an example analysis of different types of the mineral charoite, we have shown that the time variation of the ratio of radiation fluxes in selected spectral ranges spanning the UV, visible, and IR regions can be used for analytical purposes to identify or differentiate materials, and is an additional source of information about the sample.
