Structural and luminescent properties of Eu2+ and Nd3+-doped mixed alkaline earth aluminates prepared by the sol-gel method

摘要

Alkaline earth aluminates with the overall nominal compositions Mg 0.5 Sr 0.5 Al 2 O 4 (MSA), Ca 0.5 Mg 0.5 Al 2 O 4 (CMA) and Ca 0.5 Sr 0.5 Al 2 O 4 (CSA) doped with 0.5 mol% of Eu 2+ and 0.25 mol% of Nd 3+ ions were obtained by a modified aqueous sol-ge
