Abstract
We have extended our room-temperature hole burning studies, first performed on SrFCI0.5Br0.5: Sm2+ mixed crystals [1], to a wider class of single crystal materials with general composition MeIyMeII1-y YXIxXII1-x: Sm2+(Me=Ca,Sr,Ba; Y=F,H; X=CI,Br,l). This allowed to widen the spectral range for hole burning and to study the functional properties in dependence of the material structure. Because of the possibility to vary the composition (x,y) almost continuously and because of the relatively simple description of the disorder in the mixed crystals the formation of inhomogeneous broadening could have been described in a very detailed manner in these materials [2]. The above mentioned reasons make it enticing to study also the electronic and ionic movements through the hole burning at elevated temperatures.
