Although multiple emissive phosphors are of great fundamental interest and practical importance, it is still challenging to achieve full-color tunable luminescence in a single-component material. Herein, we present an antimony-doped lead halide single crystal (C₁₀NH₂₂)₂PbBr₄: Sb³⁺ with widely tunable red/green/blue/white luminescence. Extrinsic Sb³⁺ dopants provide host another active sites to capture photo-generated excitons, thus triggering blue/red dual emission. Moreover, a reversible thermal-induced phase transition transforms blue/red emission into green/red dual emission. Both two phases exhibit intriguing excitation-wavelength dependent emission, affording a whole color gamut covering the red-green-blue (RGB) color triangle on the CIE 1931 diagram. Experimental and theoretical calculation studies reveal two emitters work independently, which paves the way for the multimode optical control and promotes the development of multifunctional luminescent materials.

尽管多种发光荧光粉具有重要的基础意义和实际意义，但在单组分材料中实现全色可调发光仍然具有挑战性。在此，我们提出了一种具有广泛可调红/绿/蓝/白发光的锑掺杂卤化铅单晶(C ₁₀ NH ₂₂ ) ₂ PbBr ₄ : Sb ^{3+ 。}外在锑³⁺掺杂剂为宿主提供了另一个活性位点来捕获光生激子，从而触发蓝/红双发射。此外，可逆的热诱导相变将蓝色/红色发射转变为绿色/红色双发射。这两个阶段都表现出有趣的激发波长相关发射，提供了覆盖 CIE 1931 图上红-绿-蓝 (RGB) 颜色三角形的整个色域。实验和理论计算研究表明，两个发射器独立工作，为多模光学控制铺平了道路，促进了多功能发光材料的发展。
