Synthesis and study of europium doped BaI2 in glass ceramic form

Popis výsledku v původním jazyce

Present paper reports an approach to BaI2:Eu2+ glass ceramics fabrication from a powder route. X-ray diffraction analysis made evidence for the glass ceramics containing BaI2·2H2O and BaI2 inclusions when 50 wt.% of the starting iodide powder had been used in the synthesis process. According to scanning electron microscopy, the samples with initial mix of 25 and 50 wt.% of the BaI2:Eu2+ demonstrated presence of ceramics particles inside. Photoluminescence spectra were multicomponent in these samples as compared to the single band spectrum observed in the BaI2:Eu2+ powder. Altogether this indicates europium distribution over several places with different environments in the materials. BaI2 dissolution in the glass matrix is confirmed further by electron paramagnetic resonance measurements. They have shown that the Eu2+ ions predominantly stay in the glass, not ceramic grains.
