Abstract:The influence of cooling history for the Zn 3 Ga 2 Ge 2 O 10 /Cr 3+ phosphors prepared by solid state reaction on the spectral properties was discovered, and an anticounterfeiting scheme based on the identification with smartphone was proposed and experimentally demonstrated using the studied phosphors. A combination of colortunable visible fluorescence emission and near-infrared (NIR) afterglow emission in Zn 3 Ga 2 Ge 2 O 10 /x mol % Cr 3+ (x = 0, 0.05, 1, 2, 3, and 4) phosphors to achieve multimode anticoun… Show more
