The main interest of the studies was the very effective E-V transfer especially for Cs halides which leads to intense vibrational luminescence (VL) (see in Fig. 5.3). Even superfluoresence [.] and

Investigation of these centers allows one to study the influence that a change in electron density has on the molecule, thereby simulating the effects occurring during the excitation/relaxation cycle of a F.(CN.).

While the E-V energy transfer cannot be observed directly for F.(OH.) centers by the occurrence of vibrational luminescence (owing to the presence of effective nonradiative channels) and more difficult resonance Raman studies have to be emp

From this viewpoint the quenching of F luminescence in OH.-doped samples can be readily explained by analogy to the well-known quenching of the emission at high F-concentrations.

Their most common charge state is the trivalent positive one, which is unfavorable for incorporation into alkali halides. However, Eu., Yb., and Sm. also exist as divalent ions with high enough ionization energies to be stable. The
