Short-Wave Infrared Emissions from Te4+–Ln3+ (Ln: Er, Yb)-Codoped Cs2NaInCl6 Double Perovskites

Published in Chemistry of Materials, 2023

My contributions:

  • Optimized hydrothermal synthesis parameters for the doped double perovskites to fine-tune stoichiometry and maximize SWIR emission efficiency.
  • Characterized dopant site incorporation, doping percentages, and lattice distortion using PXRD and ICP-MS.
  • Conducted temperature-dependent (8–300 K) photoluminescence excitation, emission, and lifetime measurements to elucidate the energy-transfer mechanisms driving SWIR emission.
  • Fabricated a prototype phosphor-converted light-emitting diode (pc-LED) using the optimized double perovskite phosphors.
