Lead-free double perovskite halides are emerging optoelectronic materials that are alternatives to leadbased perovskite ***,single-crystalline double perovskite halides were synthesized,and their intriguing functional properties were *** such pioneering works,lead-free double perovskite halides with better crystallinity are still in demand for applications to novel optoelectronic ***,we realized highly crystalline Cs2AgBiBr6 single crystals with a well-defined atomic ordering on the microscopic *** avoided the formation of Ag vacancies and the subsequent secondary Cs3Bi2Br9 by manipulating the initial chemical environments in hydrothermal *** suppression of Ag vacancies allows us to reduce the trap density in the as-grown crystals and to enhance the carrier mobility *** design strategy is applicable for fabricating other lead-free halide materials with high crystallinity.
