摘要：

VUV emission of several stoichiometric fluoride crystals containing Er3+ and Tm3+ ions (LiErF4, LiTmF4, KErF4, KTmF4, BaTm2F8) has been studied with the technique of time-resolved spectroscopy under the pulsed synchrotron radiation excitation. Both fast (nanosecond) and slow (microsecond) VUV emission was detected for Tm3+-containing compounds in the studied spectral range (150-200 nm) while for Er3+-containing crystals only fast emission is observed. The difference is due to different energy level schemes for high-lying 4f states of these ions. In case of Er3+ the energy position of some high-lying 4f states is very close to that of emitting 5d levels and so the concentration quenching leads to considerable shortening of the emission.
