    Improved NIR Afterglow for Microenvironment Fluorescence Detection

## Description

- description: Recently, combining long afterglow materials with organic fluorescent
    dyes, particularly carbon dots (CDs) to produce heterojunction and improve its
    luminescence and persistence properties became an important research direction.
    However, the precise role of these internal defects in the energy transfer process
    of CD@inorganic matrix composite fluorescent materials has not been thoroughly
    discussed. Establishing matching trap level to promote the energy transfer between
    the trap level and CDs level not only helps to enhance the afterglow performance,
    but also can explain the heterogeneous structure interaction between organic–inorganic
    fluorescent materials. Herein, ZLAGC@CDs luminescent composite is successfully
    synthesized via coating CDs on Zn1-x(Li/Al)xGa2xO4:0.005Cr3+ (ZLAGC, x = 0–1),
    which exhibits a unique double emission at ≈430 nm (the defect luminescence of
    CDs) and 718 nm (the 2E→4A2 transition of Cr3+). After coating, the energy transfer
    from the defect level of CDs to the excited state of Cr3+ enhanced the NIR emission.
    The electron transfer between the defect level of CDs and the split deeper trap
    level of ZLAGC also improved the visible and near-infrared (NIR) afterglow. The
    fluorescence and afterglow signals of ZLAGC@CDs are highly sensitive to solution
    pH under acidic conditions, indicating that the prepared fluorescent composite
    has potential application in acid microenvironment fluorescence detection.
