Overview

Mixed-anion compounds optimize phosphor color tunability in solid solutions, indicating improved LED performance.

Key Points

  • Main finding: Rare-earth substitution in La3Si2S8I enhances photoluminescence and color tunability.
  • Key evidence: Phosphors exhibit absolute quantum yields up to 50% and wide visible color emission.
  • Approach: Solid solutions (La1-xREx)3Si2S8I were developed with different rare-earth ions for study.
  • Significance: These phosphors are promising for efficient energy-conversion in white light-emitting diodes.
