Spatial halide exchange reactions for sculpting light in hybrid perovskites.
Review in RSC advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hybrid perovskites have emerged as transformative materials in optoelectronics because their halide composition enables wide and controllable changes in bandgap and photoluminescence. Yet, translating this compositional tunability into spatially programmed optical functionality remains challenging. This review focuses specifically on spatially controlled halide exchange in hybrid and related lead-halide perovskites, emphasizing how the location, kinetics, and confinement of ion exchange determine the resulting optical landscape. We critically compare light-mediated/photocatalytic, laser-assisted, lithographic, solution-solid, solid-solid, and vapor-phase strategies in terms of localization mechanism, processing time, spatial resolution, compositional stability, scalability, and demonstrated functionality. Particular attention is given to vacancy-assisted ion migration, concentration gradients, interfacial diffusion, and optically driven precursor accumulation as the mechanistic basis of spatial control. We distinguish experimentally demonstrated outcomes-such as localized multicolor emission, compositionally graded nanowires, and single-crystal heterojunctions-from applications that remain prospective, including fully integrated micro-LED arrays and complex photonic circuits. The review identifies a central trade-off between spatial precision and throughput/stability and proposes standardized reporting of feature size, exchange time, compositional fidelity, and post-exchange stability as priorities for moving spatial halide exchange toward practical devices.
