Composition dependence of Pr3+ spectral characteristics in strontium lanthanum aluminate crystals
Source abstract
Abstract
An analysis of the high resolution spectra of the Pr 3+ in strontium lanthanum aluminates, charge compensated with magnesium Sr 1-x Pr y La x-y Mg x Al 12-x O 19 , (on a large composition range) is presented. The spectra are mainly dependent on the composition parameter x, and show more Pr 3+ centers, two of them stable. Based on composition dependence and polarization data, structural models for the main two centers are proposed.
