Water‐Resistant Perovskite Polygonal Microdisks Laser in Flexible Photonics Devices

Three kinds of polygonal 2D single-crystalline microdisk (MD) laser resonators of MAPbBr3 in square, hexagonal, and octagonal shapes are controllably prepared using a facile one-step solution self-assembly method by regulating the growth kinetics. Furthermore, polygonal MDs are embedded in water-resistant polymer thin-film with high flexibility and transmission as flexible photonic devices.
