## Title

- title: Achieving high-performance far-red emission in Cr3+-activated garnet phosphors
    via Ca2+/Zr4+ doping toward plant lighting
  title_type: original
  lang: en

## Description

- description: 'Equimolar Ca2+ and Zr4+ doping was implemented to establish novel
    garnet-type Gd3−xCaxAl2.95Ga2−xZrxO12:0.05Cr3+ (x = 0–2.0) far-red (FR) phosphors.
    The quantum efficiency and temperaturedependent luminescence analysis successfully
    produced the optimal x = 0.5 phosphor, which exhibited highly efficient (IQE =
    92.8% and EQE = 31.6%) broadband FR-emission peaking at ∼714 nm (full-width at
    half-maximum ∼81 nm) and excellent thermal stability (95.5% at 423 K) under 450
    nm light excitation. Its performance is superior to that of most reported Cr3+-activated
    FR-emitting garnet phosphors, and its emission spectrum can well superpose with
    the absorption band of the far-red phytochrome, endowing this phosphor with huge
    potential application in the construction of high-quality FR pc-LEDs used for
    plant lighting. '
