This study demonstrates the emission enhancement of Al 3+ co-doped SrZn 2 (PO 4 ) 2 :Eu 2+ ,Mn 2+ phosphors. The crystallinity and emission mechanism were investigated, and the results indicate that co-doping with Al 3+ increased the atomic concentra

The influence of In 3+ doping on the binding energy of ions and the energy transfer mechanism of white SrZn 2 (PO 4 ) 2 :Eu 2+ ,Mn 2+ phosphor was investigated. The ligand fields around Sr 2+ and Mn 2+ varied with different kinds of doped ions, while
