By now it has been eight weeks during which we have been working from home. This time is obviously very difficult for everyone.

We are thus very happy about some good news: our work on broad luminescence bands in two-dimensional halide perovskites was just published by Nature Communications

In this paper, a concerted effort by our spectroscopists, Simon, Eelco and Herman, was made to show that the broad emission bands in our isngle crystals cannot be explained through the predominant narrative of exciton self-trapping. Instead, we identified trap states as their origin.
