## Description

- description: A series of CaGdAlO4-type layered perovskite phosphors showing deep
    red luminescence (λem = 711 nm, λex = 338 nm) were synthesized via solid reaction.
    A comprehensive analysis via photoluminescence, X-ray photoelectron spectroscopy,
    thermoluminescence, and fluorescence decay revealed that the deep red luminescence
    is related to oxygen defects and particularly oxygen interstitials. The defects
    related luminescence was effectively regulated through partial substitution of
    multi-cationic sites (the Ca2+ site with Mg2+, Sr2+, Ba2+; the Gd3+ site with
    La3+, Y3+, Lu3+) and full substitution of the Gd3+ with Y3+. Remarkably, a 383.3%
    stronger luminescence was obtained through partial substitution with Lu3+, and
    the quantum yield of luminescence reached 28.74% which is higher than those of
    the most previously reported self-luminescence systems. A pc-LED device was fabricated
    with the phosphor, and the device was showed to have potential application in
    indoor plant cultivation.
