## Description

- description: 'The near-infrared (NIR) light of 900-1100 nm exhibits enormous application
    potential in fields such as optical communication and biological detection. However,
    high-efficiency phosphors emitting beyond 900 nm remain extremely limited due
    to non-radiative deactivation. In this study, a 455 nm blue light excitable NIR
    phosphor that efficiently emits in the wide range of 700-1200 nm (peaking at ~960
    nm) was obtained through Cr3+/La3+ codoping of Ruddlesden-Popper type Sr3Zr2O7
    perovskite, whose internal/external quantum efficiencies (%) and thermal stability
    of luminescence (I423/I298, %) reached ~92.4/57.5 and 73, respectively. Experimental
    and theoretical analysis found the decisive role of the La3+ codopant in Cr3+
    luminescence: it not only inhibited Cr3+ from oxidation but also attracted the
    Cr3+ ions to aggregate around it to form Cr3+-Cr3+ pairs for the aforesaid excellent
    luminescence. Combining the NIR phosphor with a Si-PIN photodetector created a
    highly effective blue-to-NIR conversion unit, demonstrating application potential
    of the phosphor for underwater wireless optical communication (UWOC).'
