In article number 1800295 , Sang‐Wook Kim and co‐workers report highly stable perovskite nanocrystals with cesium and rubidium. Their stability under UV and heat results from an increased defect‐formation resistance and exciton binding energy with Rb + incorporation. This work helps mitigate the biggest weakness of perovskite structures and, thus, increase their applicability. The cover art image depicts alive CsRbPbX 3 perovskite quantum dots under hot lava, which emit green and blue light.
