A new composition of phosphor material AlON:Er 3+ codoped with Mg 2+ were prepared by solid‐state reaction method. The effect of Mg 2+ dopants on upconversion luminescence properties of the AlON:Er 3+ phosphor was investigated. At certain concentrations, Mg 2+ dopants were found to greatly enhance the red emission intensity of AlON:Er 3+ phosphors. From our results, the enhancement of the emission intensity by Mg 2+ dopants was discussed in terms of the Er 3+ distribution in crystal lattice and crystal symmetry by introducing oxygen vacancy.
