Efficient energy transfer from organic triplet states to Mn²⁺ dopants for dynamic tunable multicolor afterglow in 1D hybrid cadmium chloride.

ABSTRACT: Metal ion-doped organic-inorganic hybrid metal halides have emerged as promising room-temperature phosphorescence (RTP) materials owing to their tunable afterglow properties and significant potential in information security applications. However, optimizing RTP performance and achieving dynamic control over afterglow colors remain challenging in 1D hybrid systems, primarily because of the inefficient energy transfer from RTP-active organic components to external emissive sites. Herein, we report a novel 1D hybrid metal halide benchmark material, [(NBP)Cd₂Cl₅H₂O] (NBP-Cd, NBP = N-benzylpiperidone), and a series of Mn²⁺-doped derivatives, NBP-Cd:xMn²⁺ (where x represents doping levels from 1% to 50%).
