摘要：
FAPbBr(2+) composite perovskites consisting of 0D FA(4)PbBr(6) and 3D FAPbBr(3) have been synthesized by a solid state reaction. Due to the endotaxy passivation of FAPbBr(3) by FA(4)PbBr(6), FAPbBr(3) crystals were stably deformed without agglomeration from the cubic to the orthorhombic structure by compression, which led to a significant PL enhancement.
