In this study, the fabrication of a large bulk crystal based on the hybrid structure of CH3NH3PbBr3 (MAPBr) and PbS quantum dots (QDs) with excellent crystal lattice match using an in situ epitaxial crystallization technique is presented. The hybrid bulk crystal is successfully constructed by uniformly dispersing PbS QDs within the MAPBr matrix. The crystalline growth method is also changed to achieve the desired hybrid structure. The light emission range is modulated and the light emission lifetime is prolonged by constructing a MAPBr‐PbS hybrid structure. Additionally, the hybrid bulk crystal exhibited an up‐conversion effect, which does not appear in MAPBr single crystal. These findings highlight the promising potential of the MAPBr‐PbS QDs hybrid bulk crystal in the fields of optics and photoelectronic, such as all solid‐state lasers, bio‐imaging, optical data storage, and photovoltaic applications. This in situ hybrid crystallization technique also provides a universal pathway for the preparation of other bulk crystals based on perovskite‐QDs hybrid structures.

Halide perovskites have generated tremendous interest for photodetectors (PDs), mainly because of their unique optoelectronic properties, wide wavelength coverage, and facile fabrication process. Perovskite single crystal thin films (SCTFs) characterized by their grain‐boundary‐free structures and thin thickness are expected to enhance the optoelectronic performance and broaden applications of PDs. In this review, the latest progress in perovskite SCTFs is examined, emphasizing main synthesis technologies, strategies for integrating SCTFs within devices, and applications in photodetection. Besides, the classical synthesis methods for perovskite SCTFs are analyzed in detail elucidating the respective advantages and limitations. Moreover, proper integration of perovskite SCTFs into devices is one of the prerequisites for the potential optoelectronic device fabrication, and three main strategies are discussed thoroughly including the transfer of synthesized single crystals for electrode deposition, in situ growth of SCTFs on the electrode/substrate, as well as in situ growth of SCTFs on the transport layer. Along with interface engineering strategies which energized high‐performance SCTF PDs, the applications for high‐performance SCTF PDs including flexible PDs, PD arrays for imaging, and narrowband photodetection are further analyzed. Finally, the future opportunities of perovskite SCTFs are presented, with the expectation of stimulating new ideas and further advances on designs for superior‐performance PDs.
