Abstract The ever‐increasing counterfeiting issues have triggered a research upsurge in multi‐modal fluorescence anti‐counterfeiting materials. All inorganic metal halide double perovskites possess the advantages of facile preparation procedures and high thermal stability, which also provide suitable doping sites to regulate emission behavior highlight potential for serving as Herein, series Sb 3+ , Er Yb solely or codoped Cs 2 NaLuCl 6 are successfully prepared, optical properties dependent on ratio lanthanide ions (Ln ). Notably, due participation energy‐transfer cross‐relaxation processes, tri‐doped (0.3%Sb ‐20%Er ‐50%Yb ‐Cs ) shows luminescence responses excitation sources with different photon energies, is employed construct patterns by combining .

Chiral organic-inorganic hybrid metal halides as promising circularly polarized luminescence (CPL) emitter candidates hold great potential for high-definition displays and future spin-optoelectronics. The recent challenge lies primarily in developing high-performance red CPL emitters. Here, coupling the f-f transition characteristics of trivalent europium ions (Eu3+) with chirality, we construct chiral Eu-based halides, (R/S-3BrMBA)3EuCl6, which exhibit strong predictable emission large photoluminescence quantum yield (59.8%), narrow bandwidth (≈2 nm), long lifetime ms), together dissymmetry factor |glum| 1.84 × 10−2. Compared previously reported these show highest brightness. Furthermore, degree polarization (R/S-3BrMBA)3EuCl6 can be manipulated by external magnetic field. Particularly, benefiting from field-generated Zeeman splitting spin mixing at exciton states, an anomalously positive magneto-photoluminescence was observed room temperature. This work provides efficient strategy constructing both pure-red It also opens door rare-earth toward optoelectronic spintronic applications. perovskites are materials luminescence. Here authors present leading to magneto-chiroptical properties.
