espanolPresent paper reports an approach to BaI2:Eu2+ glass ceramic fabrication from a powder route. The structural, morphological, luminescent and paramagnetic properties of the materials synthesized this way have been investigated. X-ray diffraction analysis made evidence for the glass ceramics containing BaI2·2H2O and BaI2 inclusions when 50wt.% of the starting iodide powder had been used in the synthesis process. According to scanning electron microscopy, only two samples demonstrated presence of ceramics particles inside: those with initial mix of 25 and 50wt.% of the BaI2:Eu2+. Photoluminescence spectra could be measured only in these samples. They were multicomponent 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 avoiding ceramic grains. Only negligibly small amount presumably occupies the ceramic part in the sample with the initial 50wt.% part of the BaI2 powder. The Eu2+→Eu3+ charge transformation under 442nm laser light irradiation has been observed in the glass ceramics as well. EnglishEste articulo informa sobre el enfoque de sintesis de BaI2:Eu2+ vitroceramica a partir de una ruta de polvo. Se han investigado las propiedades estructurales, morfologicas, luminiscentes y paramagneticas de los materiales sintetizados de esta manera. El analisis de la difraccion de rayos X habia demostrado las vitroceramicas que contienen inclusiones de BaI2·2H2O y BaI2 cuando el 50% en peso del polvo de yoduro se habia utilizado en el proceso de sintesis. Segun la microscopia electronica de barrido, solo dos muestras demostraron la presencia de particulas de ceramica adentro: aquellas con una cantidad inicial del 25 y 50% en peso del BaI2:Eu2+. Los espectros de fotoluminiscencia solo se pudieron medir en estas muestras. Eran multicomponentes en comparacion con el espectro de banda unica observado en el polvo BaI2:Eu2+. En conjunto, esto indica la distribucion de europio en varios lugares con diferentes ambientes en los materiales. La disolucion de BaI2 en la matriz de vidrio se confirma, ademas, por mediciones de resonancia paramagnetica electronica. Han demostrado que los iones de Eu2+ permanecen predominantemente en el vidrio, evitando los granulos de ceramica. Solo una cantidad insignificantemente pequena ocupa presumiblemente la parte ceramica en la muestra con el 50% en peso del polvo inicial de BaI2. La transformacion de carga de Eu2+→Eu3+ bajo irradiacion de luz laser de 442nm tambien se ha observado en la vitroceramica.
