摘要：

In this work, we probe the photodegradative behaviour of CsPbBr3 perovskite nanocrystals under illumination intensities in excess of 1 W/cm(2). In doing so, we uncover optical behaviours unique to this extreme form of degradation - namely a pronounced period of increasing photoluminescent intensity at the outset of degradation along with a red-shifted emission lobe. We also compare the photochemical lifetimes of CsPbBr3 to the relating organic-inorganic hybrid of FAPbBr(3) and show that FAPbBr(3) can withstand such high intensities for approximately ten times longer than CsPbBr3. This marks out FAPbBr(3) as a potential successor to CsPbBr3 in optoelectronic applications.
