Tuning the Bi3+-photoemission color over the entire visible region by manipulating secondary cations modulation in the ScVxP1−xO4:Bi3+ (0 ≤ x ≤ 1) solid solution

摘要: Unlike rare earth (RE) (e.g., Eu2+) and non-RE Mn2+) doped tunable solid solutions that frequently suffer from the visible re-absorption issue, Bi3+ ion features remarkable advantages of a strong UV excitation intensity an tail less than 430 nm, giving potential to solve issue for future lighting technology. Herein, we report type zircon-type ScVxP1−xO4:Bi3+ (0 ≤ x 1) emission-tunable solution has yet no significant light absorption. We reveal gradual substitution larger V ions smaller P ions, which means expansion lattice cell, can shift edge 295 385 340 425 nm emission position 455 641 without causing large change Stokes shift. This spectral shifting is found be consequence complex dependence intra-ion charge-transfer related transitions with crystal structure. Owing excitation-triggered multi-emission properties, then discover serve as material anti-counterfeiting information protection applications. work provide design insights into discovering more RE in future, through modulation secondary cations isostructural crystals.
