## Description

- description: "Cr3+-activated near-infrared (NIR) phosphors are the most promising
    materials for commercialization.\r\nHowever, the emission of most Cr3+-activated
    phosphors is typically located in the NIR-I region and\r\nachieving luminescence
    towards the NIR-II region (4900 nm) via Cr3+ doping remains challenging. This
    study reports a novel Cr3+-activated NaBaScSi2O7 phosphor that exhibits broadband
    NIR emission centred at 974 nm with a full width at half maximum of 140 nm under
    493 nm blue light excitation. The emission wavelength exceeds that of most Cr3+-activated
    NIR phosphors. The underlying mechanism for the encouraging phenomenon is attributed
    to the strong charge polarisation arising from the intrinsic local coordination
    environment of the Cr3+ ions, as confirmed by charge differential density (CDD)
    and the electron localization function (ELF) analyses. The photoluminescence properties
    of phosphors were systematically investigated, and the performance of the fabricated
    NIR pc-LED device was evaluated for night vision and non-invasive imaging. Notably,
    the NaBaScSi2O7 phosphor displayed a bright green colour with excellent colour
    properties and its potential as a stable green ceramic pigment was explored."
