cathodoluminescence
Cathodoluminescence mapping is used to observe Halide-segregated Methylammonium-free wide bandgap perovskites
A new paper called ‘Nano-emitting Heterostructures Violate Optical Reciprocity and Enable Efficient Photoluminescence in Halide-Segregated Methylammonium-Free Wide Bandgap Perovskites’ was recently published in ACS Energy Letters by the researchers from University of Potsdam, Helmholtz-Zentrum Berlin and École Polytechnique Fédérale de Lausanne.
