Zero-dimensional (0D) indium hybrids have been recently explored as promising platforms for use in solid-state lighting owing to their environmental friendliness and stability. Herein, we first designed a novel 0D indium hybrid (TEA)2InCl5 (tetraethylammonium+, C8NH20+), where the organic cation (TEA)+ cocrystallizes with five-coordinated [InCl5]2− square pyramids. Experimental data and first-principles calculations reveal that the blue emissions are attributed to the organic cations (TEA)+ and self-trapped excitons (STEs) in the inorganic [InCl5]2− square pyramids. Remarkably, when incorporating Sb3+ ions, the value of photoluminescence quantum yield (PLQY) is greatly enhanced to 78.85%, and the emission color could be tuned from blue to warm white and finally to orange-red. This success of (TEA)2InCl5 : Sb3+ not only enriches the structure and optical properties of 0D indium hybrids, but also provides a new direction towards modulating the optical performance through a doping strategy.

零维铟杂化物和 Sb 掺杂调制光致发光
零维 (0D) 铟杂化物由于其环境友好性和稳定性，最近被探索为用于固态照明的有前途的平台。在此，我们首先设计了一种新型 0D 铟杂化物 (TEA) 2 InCl 5（四乙基铵+ , C 8 NH 20 +），其中有机阳离子 (TEA) +与五配位 [InCl 5 ] 2−方形金字塔共结晶。实验数据和第一性原理计算表明，蓝光发射归因于无机物 [InCl 5 ] 2−中的有机阳离子 (TEA) +和自陷激子 (STE)方形金字塔。值得注意的是，当掺入Sb 3+离子时，光致发光量子产率（PLQY）的值大大提高到78.85%，发光颜色可以从蓝色调到暖白色，最后调到橙红色。(TEA) 2 InCl 5 : Sb 3+的成功不仅丰富了0D铟杂化物的结构和光学性质，而且为通过掺杂策略调制光学性能提供了新的方向。
