Multimodal luminescent materials integrating spectral and temporal information are highly desirable for dynamic optical information encoding. However, constructing such systems often requires complicated molecular design or multiple synthetic steps. Herein, we report a simple Sb-introduction strategy to regulate excited-state dynamics in the zero-dimensional (0D) organic–inorganic hybrid metal halide (AP)₂ZnCl₄ (AP = 2-aminoacetophenone). The pristine host intrinsically combines prompt AP⁺ fluorescence with long-lived AP⁺-derived room-temperature phosphorescence (RTP). Upon Sb introduction, an additional broad Sb-related localized/self-trapped excitonic emission appears and the excited-state relaxation kinetics are redistributed while the native RTP pathway remains operative. These composition-dependent responses enable a proof-of-concept sequential time-gated optical encoding/decoding scheme with “WWW”, “SUV”, and “RTP” outputs. The results highlight dopant-mediated excited-state regulation in 0D hybrid metal halides for dynamic optical information encoding.

An on-chip full-Stokes polarimeter using 1D chiral-polar perovskite ( R / S -NEA)PbI ₃ provides self-powered, low-noise operation. It achieves sub-percent Stokes accuracy, and ultra-high weak-light sensitivity for imaging.

The SnO₂/Sn₄P₃ heterojunctions encapsulated within hierarchical carbon frameworks generate a built-in electric field, while the dual-carbon confinement buffers mechanical strain and guides LiF-rich SEI formation.

We illustrate the yolk–shell structure of SnSe ₂ @NC, highlighting its robust architecture for stable sodium storage. At a high current density of 5 A g ⁻¹ , it delivers an impressive capacity, demonstrating its superior performance as an SIB anode.

In this work, PbPd_0.9V_0.1O₂ and PbPd_0.9Gd_0.1O₂ films with (002) preferred orientation were prepared using a pulsed laser deposition technique. The positive CER effect were found in V and Gd doped films, and its physical mechanism was investigated.
