<title>Abstract</title>
<p>Natural and synthetic scheelite are investigated by time-resolved laser-induced luminescence to detect and ascribe various luminescence lines to a variety of <italic>REE</italic>. The selectivity of detection is possible by using different time delays after excitation, different gate widths and different excitation wavenumbers and allowed to detect <italic>REE</italic> in samples where they are hidden by intrinsic luminescence and not visible in the steady-state spectra as well as by cathodoluminescenee. Luminescence of Pr<sup>3+</sup>, Er<sup>3+</sup> and Tm<sup>3+</sup> are detected even with low concentrations and in the presence of Tb<sup>3+</sup>, Dy<sup>3+</sup> and Sm<sup>3+</sup>. Luminescence of Ho<sup>3+</sup> and Yb<sup>3+</sup> is firstly detected in natural scheelites and luminescence of Eu<sup>2+</sup> and Ce<sup>3+</sup> is preliminary suggested.</p></abstract>
