Overview

Research demonstrates enhanced luminescence in Sb3+-doped perovskites, revealing implications for optical properties and electronic structure.

Key Points

  • A non-degenerate triplet state was successfully achieved, enhancing luminescence across a broad spectrum of 350–750 nm.
  • The study identified specific split energy levels in the SbCl3− compound due to spin-orbit coupling and Jahn-Teller effects.
  • Research utilized a novel 2D Sb3+-doped (PXA)2NaInCl8 double perovskite to explore the interplay of structural perturbations and luminescence.
  • The physical model reveals the role of SOC and JTE in modulating luminescence, calling for future studies on related materials.
