Near-bandgap emission in [HOC <sub>2</sub> H <sub>4</sub> NH <sub>3</sub> ] <sub>2</sub> PbI <sub>4</sub> perovskite under hydrostatic pressure: emission of a free exciton and a polaronic exciton
As hydrostatic pressure increases, the polaron formation energy in EA 2 PbI 4 increases and therefore the emission of free exciton (FE) containing a large polaron (FEP) is enhanced and redshifts by a factor of 1.5 relative to the FE emission.
