Chameleon affords: The foundation of shade variation in low-dimensional perovskites

Wide-field photoluminescence micrographs (230_175 μm) show how somePerovskite flakes appear bright green over their entire area (left panel), whilst other flakesexhibit a distinctly red-shifted emission (right panel).

Scientists from the…

Scientists from the University of Groningen have now shown that in some cases, the explanation of why…
