The photoluminescence intensity of Eu 2+ emission increased with increase in the doping concentration of Eu 2+ up to 15 at %. The photoluminescence intensity of BaMgAl 10O 17: Eu 2+ also varied with the EG: CA ratio. SEM investigation indicates that the sol-gel derived particles exhibited an irregular shape. The EPR studies showed that Eu 2+ ions occupied the sites with non-cubic symmetry in the prepared phosphors. |
