摘要： 本实验制备了不同浓度的Sb3+掺杂有机-无机卤化物(TMA)2ZrCl6(TMA = C4H12N)杂化微晶，其具有有趣的激发波长依赖性发光。(TMA)2ZrCl6:Sb3+中的多激子发射模式通过控制激发波长实现了动态颜色变化。该杂化微晶材料的可调谐发射、高效发光(光致发光量子产率高达94.31%)和出色的环境稳定性在防伪和固态照明方面具有独特的应用。本实验操作简单、制备容易、实验时间短，并且在不同波长下的颜色变化丰富多彩，有利于吸引观众注意并认识到不同发光的原理。

Abstract: 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.
