“…Nevertheless in CdF 2 :Mn 2+ and CaF 2 :Mn 2+ [24], where it is well known that the 3d ion-ligand distance is large, Dq values similar to the one found in our glass have been found. In the same way, the B and C parameters for the most concentrated samples in chlorine and bromine ions are similar to those obtained in chloride and bromide crystals but the Dq values are smaller than in crystals [19,[26][27][28][29]. Some authors indicate that this effect is due to the fact that the 3d ion is placed in the Ba 2+ ion position, which has a large ionic radius and a very strong modifier character in ZBLAN glasses [12].…”

Some manganese doped fluorozirconate, fluorochloro- and fluorobromozirconate glasses have been prepared following and improving some standard methods. Electron probe microanalysis has been carried out to obtain the actual composition of the samples. The optical properties of ions, including steady state excitation and emission, and luminescence decay have been studied. Values of the crystal field and Racah parameters have been estimated from the excitation data. The results have been interpreted in terms of the progressive substitution of the fluorine ions in the first coordination shell of by chlorine or bromine ions. A concentration of about 6 at.% of chlorines or bromines with respect to the total number of halide ions is enough to have most of the ions coordinated to only chlorines or bromines.

The concentrations of magnetically active ions in clusters occurring in a diamagnetic two-dimensional host lattice are statistically calculated. This is done for an initial, total active ion concentration ranging from 1 to 100 niol?; and for all geometrically possible cluster types from singlets to septets, 449 in all. The model taken into consideration is a real Z(M)X,-type crystal, where it i s presumed that a direct exchange intra-layer is the only important interaction (no superexchange). These calculations are made in order to provide a basis for understanding the nature of the concentration-sensitive optical absorption bands and magnetic behaviour of some crystals containing transition metal ions.Les concentrations des ions magnetoactives qui forment des clusters dans une reseau bidimensionelle diamagnetique ont 6th calculbes par voie statistique. Cettes estimations ont 6th faites pour des concentrations initiales, totales, de 1% A 1007/, (molaire) pour touts les c1ust)ers possiblos, de singlets jusque'& septitts, 449 unites diffitrsntes. Le Model que nous avons consid6r6 est r6el un cristal de type Z(M)X2, ob nous supposons que l'itchange direct, int,racouche, est la seule interaction importante (sans suphr6change). Ces calculs ont 6th faits pour mieux comprendre la nature des bandes d'absorption sensibles la concentration et le comportement magnCtique de quelqucs cristaux contenant de ions de transition.
