A novel co-substitution strategy to enhance the luminescence performance of Zn2TiO4:Cr3+ phosphor
Cr 3+ is an ideal activator for near-infrared phosphor. Cr 3+ ions have an electronic structure in which the outermost shell is not fully filled, which makes the emission of Cr 3+ susceptible to the crystal field environment and the change of local structural. Therefore, when Zn 2+ -Ti 4+ ion pairs are replaced with Al 3+ -Al 3+ /Ga 3+ -Ga 3+ ion pairs , changes in the crystal structure and the crystal field are strengthened, which improves the luminescence performances of Zn 2 TiO 4 :Cr 3+ phosphors. The thermal stability and the intensity of the luminescence can be clearly seen to have increased.
