Anti‐counterfeiting techniques have become a global topic since they is correlated to the information and data safety, in which multimodal luminescence is one of the most desirable candidates for practical applications. However, it is a long‐standing challenge to actualize robust multimodal luminescence with high thermal stability and humid resistance. Conventionally, the multimodal luminescence is usually achieved by the combination of upconversion and downshifting luminescence, which only responds to the electromagnetic waves in a limited range. Herein, the Yb3+/Er3+/Bi3+ co‐doped Cs2Ag0.6Na0.4InCl6 perovskite material is reported as an efficient multimodal luminescence material. Beyond the excitation of ultraviolet light and near‐infrared laser (980 nm), this work extends multimodal luminescence to the excitation of X‐ray. Besides the flexible excitation sources, this material also shows the exceptional luminescence performance, in which the X‐ray detection limit reaches the level of nGy s−1, indicating a great potential for further application as a colorless pigment in the anti‐counterfeiting field. More importantly, the obtained double perovskite features high stability against both humidity and temperature up to 400 °C. This integrated multifunctional luminescent material provides a new directional solution for the development of multifunctional optical materials and devices.

多峰发光Yb3 + / Er3 + / Bi3 +掺杂的钙钛矿型单晶，用于X射线检测和防伪。
由于防伪技术与信息和数据安全相关，因此防伪技术已成为一个全球性话题，其中多峰发光是实际应用中最理想的候选技术之一。然而，实现具有高热稳定性和耐湿性的稳健的多峰发光是一个长期的挑战。常规上，多峰发光通常是通过上转换和下转换发光的组合来实现的，其仅在有限范围内响应电磁波。Yb 3+ / Er 3+ / Bi 3+共掺杂Cs 2 Ag 0.6 Na 0.4 InCl 6据报道钙钛矿材料是一种有效的多峰发光材料。除了激发紫外线和近红外激光（980 nm）之外，这项工作还将多峰发光扩展到了X射线的激发。除了灵活的激发源之外，这种材料还具有出色的发光性能，其中X射线检测极限达到nGy s -1的水平，这表明在防伪领域中进一步用作无色颜料的潜力很大。更重要的是，所获得的双重钙钛矿具有对高达400°C的湿度和温度的高稳定性。这种集成的多功能发光材料为多功能光学材料和设备的开发提供了新的定向解决方案。
