Abstract Effective online monitoring of the spatial distribution high‐energy radiation is significant importance in various fields such as medical imaging, physics, and homeland security. However, achieving detectors with both high sensitivity minimal disturbance an enormous challenge. The present study introduces a solution to this bottleneck issue through development full‐inorganic scintillating fiber, successfully demonstrating its application constructing device. activated Ce 3+ fabricated using melt‐in‐tube approach, lightweight density 2.5 g cm −3 exhibits efficient emission light yield 4000 photons MeV −1 . These characteristics enable achievement detection while keeping incident beam at minimum. Furthermore, 2D 3D monitors are constructed based on these fibers, facilitating monitoring. findings demonstrate that fibers devices offer synergistic combination negligible disturbances. This progress not only novel fiber for but also suggests promising applications nuclear where tracking essential.

Abstract 0D organic‐inorganic Cu(I)‐based halides have gained significant attention due to their low toxicity, structural adjustability, and moderate fabrication conditions. However, it is still challenging explore stable efficient hybrid that phase transition tunable spectra for multifunctional photoelectric applications. Herein, two copper halides, green‐emissive (MTPP) 2 CuI 3 yellow‐emissive Cu 4 I 6 (MTPP = Methyltriphenylphosphonium), are successfully synthesized using a slow cooling method. Both compounds exhibit high photoluminescence quantum yield (PLQY) of 81.95 99.7%, remarkable steady‐state light 38 750 63 700 photons per MeV, respectively. The scintillation screen the based on vacuum‐filtration enables X‐ray imaging resolution 17.83 18.49 lp mm −1 , showing great potential in practical Moreover, reversible fast transformation between them occurs when stimulated by ethanol or MTPP solutions, without requiring additional thermal treatment, which endows with level anti‐counterfeiting under room temperature (RT). It worth noting they display resistance water, maintaining its purity even after being immersed water 30 days. This study introduces new approach investigate Cu‐based excellent performance, stability, tunability multiple
