This study presents the preparation of Sb³⁺-doped organic-inorganic hybrid halide microcrystals, (TMA)₂ZrCl₆(TMA = C₄H₁₂N), with tunable excitation-dependent luminescence. By controlling the excitation wavelength, (TMA)₂ZrCl₆:Sb³⁺ exhibits dynamic multiexciton emission, enabling reversible color switching. The material demonstrates remarkable photoluminescence properties, including a high quantum yield (up to 94.31%), broad emission tunability, and excellent environmental stability—making it highly suitable for anti-counterfeiting and solid-state lighting applications. The experiment is designed to be simple, time-efficient, and visually engaging, with vivid color variations under different excitation wavelengths, effectively illustrating fundamental luminescence mechanisms while capturing audience interest.
