From: Degradation of black phosphorus is contingent on UV–blue light exposure
Atomic force micrographs of BP flakes showing degradation with respect to time, upon exposure to different optical wavelengths. It can be seen that the UV light causes maximum degradation followed by blue light. The degradation is observed by the appearance of bubble-like morphological features on the surface of the flakes. Scalebars denote 1 µm
