Developing light‐harvesting materials with tunable emission colors is highly desirable in applications requiring a specific color on‐demand. The modulation in material composition, structures, and polymerization can provide a useful tool for producing a wide range of emission colors. However, controlling the color gamut in a ready‐made material remains a formidable challenge. Here, several germinate‐based phosphors are reported that provide precise dynamic emission color tuning in the visible color range through the optical multiplexing of lanthanides and other ion dopants, such as lead (Pb²⁺) and manganese (Mn²⁺). The emission gamut of the developed germinate‐based materials in the full visible color range can be tuned on demand by adjusting the excitation wavelength, thereby allowing dynamic synergistic multicolor, multitemporal, and multimodal integration with ready‐made materials. The multicolored photoluminescence property of the developed phosphors is related to the different interaction modes of dopants in the crystals. Furthermore, the applications of color‐tunable phosphors in multicolor display and anticounterfeiting are demonstrated. These findings provide valuable insights toward developing next‐generation smart luminescent materials and sensors.

多响应发光材料：比变色龙材料更丰富的色彩

在需要特定颜色的应用中，非常需要开发具有可调发射颜色的光收集材料。材料成分，结构和聚合反应的调节可提供有用的工具，以产生多种发光颜色。但是，控制现成材料的色域仍然是一个巨大的挑战。在此，据报道，有几种基于发芽的磷光体通过镧系元素和其他离子掺杂剂（例如铅（Pb ²⁺）和锰（Mn ^2+））。可以通过调节激发波长来按需调整已开发的基于发芽的材料在整个可见色范围内的发射范围，从而实现与现成材料的动态协同多色，多时相和多峰集成。发达的磷光体的彩色光致发光特性与晶体中掺杂剂的不同相互作用模式有关。此外，还演示了颜色可调荧光粉在多色显示和防伪中的应用。这些发现为开发下一代智能发光材料和传感器提供了宝贵的见识。
