Abstract All‐optical logic gates (AOLGs) have attracted considerable attention for their high computing speed, low power consumption, and parallel processing; however, chemical design of new luminescent materials is a challenge to explore facile platform undertaking AOLGs. Here, an AOLG system developed based on the organic–inorganic hybrid halides [NH 3 (CH 2 ) NH ] ZnCl 6 :Mn 2+ with tricolor luminescence under dual‐wavelength excitation, intrinsic emission mechanisms are further addressed. When employing 275 365 nm UV excitations as input signals, AOLGs conduct Boolean operations “OR, YES, AND” via identifying green (G) red (R) emissions intensity ratio (R/G) output signals. This work demonstrates operation imaging image processing halide emitters, indicating promise in optical applications.

Abstract Erbium ions are commonly used to extend the photoelectric properties of metal halide perovskites from visible near‐infrared range. However, achieving high‐efficiency multimode luminescence in a single system is difficult due weak absorption associated with forbidden 4 f ‐4 transitions. In this study, unique strategy proposed adjust and enhance second region (NIR‐II) emission Cs 2 NaBiCl 6 by incorporating Fe 3+ ions. The as‐prepared material demonstrates reversible thermochromism, driven strong electron‐phonon coupling effect, exhibits tunable that can be adjusted altering excitation energy temperature. Notably, benefitting charge transfer transition ‐Cl − along influence doping on geometrical electronic structures, blue‐excitable (450 nm) NIR‐II around 1541 nm Er realized for first time, an intensity 16.7 times higher maximum photoluminescence quantum yield (PLQY) 22.5 %. This enhancement enables innovative applications such as two‐dimensional information encryption multi‐channel cooperative responses improved NIR imaging. study highlights potential optimizing perovskites, opening avenues advanced light emitting diodes (LEDs), thermometer, anti‐counterfeiting,
