Abstract:Lead-free double perovskites (DPs) have received a lot of attention owing to their good stability and environmental friendliness. They have been widely used in the field of optoelectronics because of their high quantum efficiency and long carrier migration distance. However, the application of leadfree DPs in ultrafast photonics is rarely explored. Cs 2 AgBiBr 6 , a typical lead-free double perovskite, has advantages such as toxicity free of Pb, high stability, and strong nonlinear absorption, showing great po… Show more
