Bart’s latest paper is out – congratulations!

In his recent report, Photochromism in Ruddlesden–Popper copper-based perovskites: a light-induced change of coordination number at the surface, published in Journal of Materials Chemistry C, Bart studied the origin of a reversible colour change in a copper-based halide perovskite. The intricte interplay of copper ion reduction and rearrangement of metal halide structure from octahedral to square planar are identified to change the appearance from yellow into brown.
