Optical anticounterfeiting, typically using luminescent materials to encode and unveil hidden patterns, plays an essential role in countering fraud in trademark, document security, food industry, and public safety. However, this technique is often realized through color-encoded fashion and in the visible range, preventing high-order encryption as well as visualization through scattering layers. Here, we describe a set of shortwave infrared (SWIR)-emitting lanthanide-doped nanoparticles with precisely controlled luminescence
