Abstract Recently, ns 2 metal ions (such as Bi 3+ and Sb ) doped double perovskites have captured intense attention for their efficient emission, however, achieving tunable white light emission is always an enormous challenge. Herein, /Ho co‐doped Cs KInCl 6 are proposed, the photoluminescence results show that there two bands, one broad cyan band stems from self‐trapped exciton (STE) in [SbCl ] 3‐ octahedron, while another red derives f‐f transitions of Ho . The processes can act sensitizer to activate which due energy transfer channel STE As concentration increases, luminous color be modulated orange under 315 nm irradiation, even obtained with a quantum yield 90 ± 2% when energy‐transfer efficiency 50%. Finally, single compound white‐light emitting diodes fluorescent anti‐counterfeiting labels based on 0.5%Sb /60%Ho fabricated. This work provides effective strategy achieve lead‐free through lanthanide ion co‐doping.

Abstract Long afterglow luminescent materials have captured intense attention for their unique applications in biological imaging, photodynamic therapy, and optical anti‐counterfeiting. However, achieving highly efficient tunable ultralong emission all‐inorganic metal halides is an open challenge. Herein, Sb 3+ ‐doped hexagonal CsCdCl 3 halide reported via hydrothermal reaction. Upon photoabsorption, the as‐synthesized compounds exhibit dual‐emission bands with a photoluminescence quantum yield (PLQY) of 59.6%, which can be attributed to self‐trapped exciton out strong electron‐phonon coupling. After ceasing excitation 365 nm, bright longest duration lasting up 5000 s witnessed . More importantly, color‐tunable time‐dependent realized regulating doping concentration , should due trap electrons increase gradually under high concentration. Given this unusual characteristics, anti‐counterfeiting information encryption are constructed based on compounds. These findings not only help further understand mechanism halides, but also provide new strategy designing novel materials.

Abstract 0D hybrid Sb(III) halides generally exhibit unique crystal structure and efficient emission. However, achieving white light blue light‐excited near‐infrared (NIR) emission remains an enormous challenge. Herein, a series of (18‐crown‐6@K) 2 SbX 5 (X = Cl, Br) crystals with different Cl/Br rations are synthesized via supramolecular self‐assembly. All compounds show the broadband emission, which stems from self‐trapped excitons in [SbX ] 2− pseudo‐octahedral structure. Particularly, SbCl shows tunable under various excitation wavelengths, ultra‐high luminous efficiency 92.3% is obtained 310 nm excitation. As Br gradually replaces not only bands red‐shift but also facilitate intersystem crossing process singlet to triplet excitons. Thus, independent NIR upon 450 58.2% SbBr crystals. Moreover, high‐performance single‐component light‐emitting diode (WLED) based on LED fabricated, image fusion realized. Finally, combined multiangle imaging WLED irradiation, 3D reconstruction centrifuge tube wrapped capsule successfully demonstrated.
