Dual-Strategy Optimization of Ni2+-Activated NIR Emission in CaLu2Mg2Ge3O12 via Zn2+-Drivened Internal Quantum Efficiency Boost and Cr3+-Enhanced Absorption

XGXuan GaoQWQi WangCDCong Dou

Key Points

  • The research aims to improve the near-infrared emission characteristics of phosphors by optimizing internal quantum efficiency and absorption properties.
  • Utilized a dual-strategy approach incorporating Zn2+ and Cr3+ ions.
  • Characterized the emission and absorption properties of the modified phosphors.
  • Evaluated the internal quantum efficiency enhancements.
  • Significant improvement in near-infrared emission intensity.
  • Enhanced absorption capacity due to Cr3+ doping.
  • Boost in internal quantum efficiency attributed to Zn2+ enhancement.

Abstract

Near-infrared phosphor-converted light-emitting diodes (NIR pc-LEDs) are versatile solid-state light sources, whose performance is largely governed by the properties of the NIR phosphors. Herein, we report a series of Cr3+/Ni2+...
