Abstract
- Shape control is critical and offers an efficient way to tune the properties of nanocrystals (NCs). Here we present the growth of two-dimensional (2-D) all-inorganic CsPbX3 (X = Cl, Br, I) perovskite NCs through the assembly of corresponding 1-D nanorods (NRs) under solvothermal conditions. Both 2-D CsPbX3 perovskite nanoplatelets (NPLs) and nanosheets (NSs) with a wide lateral size range from ∼100 nm to ∼1 μm and thickness of a few unit cells can be obtained by the control of the solvothermal reaction time. The present work provides a general strategy for rational fabrication of 2-D CsPbX3 (X = Cl, Br, I) perovskite NCs without the assistance of anion exchange. The obtained fluorescent 2-D all-inorganic perovskite NCs have great potential in practical photovoltaic applications. [ABSTRACT FROM AUTHOR]
