Abstract

The near-infrared (NIR) emitting wavelength-tunable

{Cr}^{3 +}

-doped barium gallate (BGO:Cr) persistent luminescence (PersL) phosphors with enhanced luminescence were reported. The emission wavelength of the BGO:Cr PersL phosphors was adjusted from 715 to 739 nm by varying the amount of

{Cr}^{3 +}

and the ratio of Ga:Ba. Meanwhile, the luminescence intensity and afterglow of the BGO:Cr PersL phosphors were enhanced. BGO:Cr PersL phosphors exhibited UV excitation, LED light restimulation, PersL for more than 6 days, and excellent capability for information storage, which was expected to promote the development of cheap and wavelength-tunable PersL materials for practical applications.
