BaI2:Eu2+,Eu3+ powders have been prepared by heat-treating BaCO3:Eu3+ precursor powders of various morphologies in an iodinating agent atmosphere and their structural properties, morphology, optical absorption, and luminescence have been studied. The results demonstrate that the powders thus prepared consist of a mixture of crystalline hydrates of various compositions, dominated by BaI2 ∙ 2Н2О (sp. gr. C2/c), and that the Eu2+: Eu3+ ratio in the powders is determined by the morphology of the precursor.
