## Description

- description: In this work, persistent luminescent phosphors of ZnGa2O4:xNi2+,yEu3+
    (termed as ZEGN) were synthesized via a traditional high-temperature solid-state
    reaction, which feature a broad emission band in the second near-infrared (NIR-II)
    window. The phosphors exhibit a broad NIR emission at about 1300 nm after ultraviolet
    (UV) or orange-red lights excitation, arising from the 3T2(3F)→3A2(3F) transition
    of Ni2+. However, incorporation of Eu3+ ions, the NIR emission intensity significantly
    increases with the increase of Ni2+ ion concentration, reaching the maximum by
    18 times at x = 0.005. Removing the light source, the sample still outputs intense
    NIR afterglow and red afterglow that can last over 500 s. It is noteworthy that
    the red afterglow of Eu3+ shows a dramatically decrease but the NIR afterglow
    increases with increasing the Ni2+ ion concentration, because of energy transfer.
    Under the excitation of 282-nm UV light, the ZGEN sample exhibits a good thermal
    stability. The phosphor offers a promising application in biological imaging due
    to broadband NIRII light and afterglow.
