Swiss Science Concentrates – A CHIMIA Column

“The authors elegantly illustrate that photoinduced lattice changes in the system are due to a specific polaronic distortion, associated with the activation of a longitudinal optical phonon mode, and show that carrier recombination reversibly unlocks structural deformation at both Br and Pb sites. These results provide a thorough description of the CsPbBr3 perovskite’s photophysics, offering novel insights on the light-induced response of the system.”
