Degradation of black phosphorus is contingent on UV–blue light exposure

Black phosphorous degradation: UV light contributes the most to photo-oxidation The ultraviolet component of the light spectrum contributes significantly to the ambient degradation of ultra-thin black phosphorous. A team led by Sumeet Walia at RMIT University in Melbourne investigated the deteriorat...
