“…Metal halide perovskites recently have demonstrated excellent performance in light‐emitting devices, due to their exceptional light‐emitting properties like high photoluminescence quantum yield (PLQY), convenient tunability of emission color, and low‐cost synthesis process, etc . Recently our group has implemented lead‐free perovskite‐based warm‐white light emitters via the emission mechanism of self‐trapped excitons (STEs) .…”

Recently, Bi‐doped Cs2Ag0.6Na0.4InCl6 lead‐free double perovskites demonstrating efficient warm‐white emission have been reported. To enable the solution processing and enrich the application fields of this promising material, here a colloidal synthesis of Cs2Ag1−xNaxIn1−yBiyCl6 nanocrystals is further developed. Different from its bulk states, the emission color temperatures of the nanocrystal can be tuned from 9759.7 to 4429.2 K by Na+ and Bi3+ incorporation. Furthermore, the newly developed nanocrystals can break the wavefunction symmetry of the self‐trapped excitons by partial replacement of Ag+ ions with Na+ ions and consequently allow radiative recombination. Assisted with Bi3+ ions doping and ligand passivation, the photoluminescence quantum yield of the Cs2Ag0.17Na0.83In0.88Bi0.12Cl6 nanocrystals is further promoted to 64%, which is the highest value for lead‐free perovskite nanocrystals at present. The new colloidal nanocrystals with tunable color temperature and efficient photoluminescence are expected to greatly advance the research progress of lead‐free perovskites in single‐emitter‐based white emitting materials and devices.

“…When t is 0.9‐1.0, it is likely to form cubic structure, which is contributed to obtain optimum electronic properties owing to strong ionic bonding. When t < 0.9 or t > 1.0, distortion of perovskite structures, changeable crystalline symmetries and different dimensionalities may appear …”

Flexible photodetectors (FPDs) have been receiving increasing attention in recent years because of their potential applications in electronic eyes, bioinspired sensing, smart textiles, and wearable devices. Moreover, metal halide perovskites (MHPs) with outstanding optical and electrical properties, good mechanical flexibility, lowcost and low-temperature solution-processed fabrication have become promising candidates as light harvesting materials in FPDs. Herein, we comprehensively review the developments of FPDs based on MHPs reported recently. This review firstly provides an introduction with respect to the performance parameters and device configurations of perovskite photodetectors, followed by the specific requirements of FPDs including substrate and electrode materials. Next, chemical compositions, structures and preparation methods of MHPs are presented. Then, the FPDs on the basis of single-component perovskite and hybrid structure perovskite are discussed, subsequently, self-powered flexible perovskite photodetectors were presented. In the end, conclusions and challenges are put forward in the field of FPDs based on perovskites. K E Y W O R D S metal halide perovskites, flexible photodetectors, self-powered

Low‐dimensional materials have pivotal significance in modern photonic, electronic, and optoelectronic areas due to their unique properties of the scale effect. Metal halide perovskites have revived in the optoelectronic fields recently, drawing intensive attention in photovoltaic devices, light‐emitting diodes, lasers, photodetectors, and so on. Compared to their three‐dimensional counterparts, the role of low‐dimensional perovskites is becoming crucial, requiring a comprehensive understanding and exploration unceasingly. In this review, we examine low‐dimensional perovskite of different forms and clarify various synthesis methods with morphological and dimensional control. Additionally, we also summarize potential optoelectronic applications based on their advantageous optical/electrical properties and enhanced mechanical integrity and stability. Finally, we propose a future perspective and possible developing directions in the exploration of novel perovskite‐derived materials, new physics, and promising applications.
