Abstract We report data on the luminescence spectra associated with photochromic centers in X-ray irradiated calcium fluoride crystals doped with Lu ions. Irradiation in low energy photochromic centers absorption band excites emission, which can be identify with transitions into photochromic centers. Ab initio calculation of absorption spectrum of photochromic center agrees rather well with experimental data.

Optical absorption spectra of X-ray irradiated alkaline earth fluoride crystals doped with divalent rare-earth ions studied by thermal bleaching
Abstract The absorption spectra of X-ray irradiated alkaline earth fluoride (CaF2, SrF2, BaF2) crystals doped with Sm, Нo, Er, Tm ions are investigated by thermal bleaching of the sample in the
Optical properties of SrF2and SrF2:Ce3+crystals codoped with In3+
In3+states are located close to electron traps and have a band character, the transfer of electrons from conduction band to the luminescence center is possible without significant trapping which

Foreign ions with d1-states in alkaline earth fluoride crystals
Starting from the model of an F-centre disturbed by an impurity ion and another centre in which the impurity ion plays an active part it is tried to explain photochromic processes in alkaline earth
Linear dichroism in photochromic CaF 2
Photochromic switching of additively colored La, Ce, Gd, or Tb doped CaF 2 with linearly polarized UV light and subsequent thermal decay of other photochromic effects leads to a linear dichroism of
Polarized Luminescence of X‐Irradiated CaF2:Y and SrF2:Y Crystals and the Structure their Luminescence Centres
Y-doped CaF2 and SrF2 crystals coloured subtractively by X-rays at room temperature exhibit a broad luminescence band at 86°K in the near infrared if they are irradiated with light of the three
Structure and properties of oxygen centers in CaF2 crystals from ab initio embedded cluster calculations
We present the results of ab initio calculations of several intrinsic and oxygen-containing defects in CaF2 including an F center, a substitutional O- ion, an O2--vacancy dipole, and F-A(O2-) and
On the luminescence and absence of luminescence of F centers
Abstract A model, proposed originally by Dexter, Klick and Russell, is used to explain the occurence or non-occurence of F-center luminescence in ionic crystals, in terms of a simple two-state
Instability of some divalent rare earth ions and photochromic effect
Abstract It was shown that the divalent rare earth ions (La, Ce, Gd, Tb, Lu, and Y) in cubic sites in alkaline earth fluorides are unstable with respect to electron autodetachment since its d 1 (e g
