## Title

- title: A new persistent luminescence phosphor of ZnGa2O4:Ni2+ for the second near-infrared
    transparency window
  title_type: original
  lang: en

## Description

- description: "Persistent luminescent phosphors of ZnGa2O4:xNi2+ (x = 0-0.01) were
    synthesized via\r\na traditional high-temperature solid-state reaction, which
    feature a broad emission band \r\nin the second near-infrared (NIR-II) window.
    Ni2+ tends to occupy Ga3+ site in ZnGa2O4,\r\nwhich results in the formation of
    oxygen vacancy. Upon ultraviolet (UV) or orange-red \r\nlights excitation, the
    phosphors exhibit a broad NIR emission at about 1300 nm, arising \r\nfrom the
    3T2(3F)→3A2(3F) transition of Ni2+. Removing the light source yields intense \r\nNIR
    afterglow, with the duration longer than 500 s. Strongest NIR emission and best
    \r\npersistent luminescence are found for the x = 0.005 sample, which is excited
    by 254-\r\nnm UV light. The ZnGa2O4:Ni2+ persistent phosphors have potential application
    in vivo \r\nimaging, because of their charming emissions and afterglows with the
    wavelength \r\nlocating in NIR-II window."
