Discovering Structure-Adaptive Oxides for Embedded Epitaxial Growth of Perovskite Nanocrystals.

ABSTRACT: Developing heterostructures presents a promising approach to enhance the performance of lead halide perovskite CsPbX₃ (X = Cl, Br, I) nanocrystals (NCs) for optoelectronic applications. Given their rich variety and extreme stability, oxide crystals are appealing candidates for integration with CsPbX₃ to expand their applications. However, heterostructural modification of CsPbX₃ with oxides remains a daunting challenge due to the substantial lattice mismatch. This study presents a strategy for constructing CsPbBr₃-in-oxide heterostructures under substantially mismatched lattice parameters by leveraging the structure-adaptive feature of rationally selected host materials. Our investigations reveal that complex oxide crystals comprising appropriate
