Laser-Induced Recrystallization of Perovskite Quantum Dots for Flexible/Wearable Light-Emitting Devices
Perovskite-structured quantum dots have received a lot of attentions to apply future light-emitting devices due to their superior optoelectronic properties. However, in normal annealing processes, perovskite quantum dots exhibited material unstability of the decreased lifetime, and the deteriorated optoelectrical properties. In this paper, we present a laser-assisted recrystallization method of perovskite quantum dots. Laser crystallized only the material through the instantaneous heating. The laser-heated material was optimized by using theoretical calculations and various material analyses.
