N2 - Laser-induced time-resolved spectroscopy of natural apatite, scheelite, zircon, calcite and fluorite enables the detection of the luminescence centers, which under steady-state conditions cannot be spectroscopically separated. By applying time-resolved spectroscopy we are able to determine rare-earth elements, luminescence of which has been previously hidden by the stronger bands of Eu2+, Mn2+, (WO4)4-, (MoO4)4- and radiation-induced centers. Luminescence of Pr3+, Tm3+ and Er3+ have been detected for the first time in minerals, also in presence of interfering ions, namely, Sm3+, Dy3+ and Tb3+ with similar emission spectra.
