Abstract Thermo‐responsive smart materials have aroused extensive interest due to the particular significance of temperature sensing. Although various photoluminescent are explored in thermal detection, it is not applicable enough X‐ray radiation environment where accuracy and reliability will be influenced. Here, a strategy proposed by introducing concept radio‐luminescent functional building units (RBUs) construct thermo‐responsive lanthanide metal‐organic frameworks (Ln‐MOFs) scintillators for self‐calibrating thermometry. The rational designs RBUs (including organic ligand Tb 3+ /Eu ) with appropriate energy levels lead high‐performance radio‐luminescence. Ln‐MOFs exhibit perfect linear response X‐ray, presenting low dose rate detection limit (min ≈156.1 nGy air s ‐1 ). Self‐calibrating based on ratiometric XEL intensities achieved good absolute relative sensitivities 6.74 8.1%K , respectively. High light yield (max ≈39000 photons MeV −1 ), imaging spatial resolution ≈18 lp mm irradiation stability (intensity ≈100% at 368 K total up 215 Gy giant color transformation visualization benefit applications, especially situ imaging. Such provides promising way develop novel photonic excellent scintillator performances.

Abstract Luminescent responsive heterostructures with region‐domained emission and integrated responsiveness exhibit great potential in information security, but always suffer from the direct exposure of fingerprint at initial state, making it easy to decode hidden confidential information. Herein, first monochromatic hydrogen‐bonded organic framework (HOF) are reported based on VIA‐group‐based hybridization toward fully‐covert photonic barcodes. Designed HOF blocks different VIA‐group elements via a configuration‐assimilation‐based assembly method generate intrinsic heterostructures. Differentiated electronegativity endows each block distinct bonding stability, which triggers actions same stimuli, finally forming multicolor mode state. These can effectively hide information, further demonstrates coding capability as high‐security anti‐counterfeiting labels. findings offer novel insight exploitation smart‐responsive hetero‐HOF systems for advanced encryption anticounterfeiting applications.
