Abstract


  • Increasing demands for optical anticounterfeiting technology require the

    development of versatile luminescent materials with tunable photoluminescence

    properties. Herein, a number of fluorescent carbon- and oxygen-doped

    hexagonal boron nitride (denoted as BCNO) phosphors are found to offer a

    such high-tech anticounterfeiting solution. These multicolor BCNO powders,

    developed in a two-step process with controlled annealing and oxidation,

    feature rod-like particle shape, with varied luminescence properties. Studies

    of the optical properties of BCNO, along with other characterization, provide

    insight into this underexplored material. Anticounterfeiting applications are

    demonstrated with printed patterns which are indistinguishable to the naked

    eye under visible light but become highly discernible under UV irradiation.

    The fabricated patterns are demonstrated to be both chemically stable in

    corrosive environments and physically robust in mechanical bending testing.

    These properties render BCNO as promising and versatile anticounterfeiting

    material a wide variety of environments.
