## Title

- title: Strategy to optimize the broadband near-infrared emission based on Eu2+-doped
    sulfureted garnet phosphors toward emerging spectroscopy applications
  title_type: original
  lang: en

## Description

- description: 'A Eu2+ doped sulfureted NIR-emitting garnet phosphor Ca3(Sc, Eu)2Si3(O,
    S)12: Eu2+ is successfully designed and synthesized. Notably, a strategy for regulating
    the initial valence state of dopants is proposed by using prepared EuS instead
    of the conventional Eu2O3 as raw material, enhancing the NIR emission by 135 %.
    Moreover, a sulfuration strategy is further introduced to enhance the NIR emitting
    intensity and internal quantum efficiency by 192 % and 167.8 %, and to improve
    thermal stability by 154 % at 120 ◦C. The luminescence origin of the unusual broadband
    NIR emission is re-examined through chemical unit co-substitution strategy by
    introducing [Al3+–Hf4+] to replace [Sc3+–Si4+] ion pairs.'
