In this study, we demonstrate that the crystallization process of CsPbIBr films can be modulated when small amounts of additives are added to the precursor solution, leading to the formation of the bright brownish α-phase perovskite films with high orientation along the [100] crystallographic direction. Doped CsPbIBr films exhibit improved crystallinity, with high coverage, large grain size and pinhole-free surface morphology, suitable for making high performance optoelectronic devices. We also explored the role of Cl in the photophysical properties of CsPbIBr perovskite films using the temperature dependent photoluminescence technique.

- SbPO is a unique monoclinic layered material known for its active lone electron pair from antimony (Sb), which leads to a distinct layered structure bound by weak electrostatic interactions with oxygen (O).
- A recent study reveals that SbPO exhibits extreme compressibility and anisotropic behavior under high pressure, particularly compressing along a specific direction due to the characteristics of the electron pair and interlayer bonds.
- Notably, at pressures above 3 GPa, SbPO transitions from a 2D to a 3D structure, with a pressure-induced phase transition occurring beyond 9 GPa, suggesting a structural change to a triclinic form, which could enhance its applications in ion intercalation and catalysis.
