N2 - For the first time, the luminescence properties
of Pr3?, Nd3? and Tm3? and Yb3? ions in fluorite crystal
have been obtained by steady-state measurements. In
addition, the luminescence spectra of Ce3?, Sm2?, Sm3?,
Dy3?, Er3? and Yb3? were measured. It was pointed out
that kexc. = 415 nm is most suitable for measuring the
Ho3? emission beside the Er3?. The emission of trivalent
holmium and erbium ions was measured independently
using time-resolved measurements and tentative assignment
of luminescence lines to C3v and C4v symmetry sites
was proposed. Besides for natural fluorite crystal, the
transitions between Stark energy levels of lanthanide ions
were presented.
