title: Small molecule-assisted fabrication of black phosphorus quantum dots with a broadband nonlinear optical response.
abstract: Ultrathin BP QDs with a uniform size of ∼3.4 nm were prepared via small molecule-assisted liquid phase exfoliation and they exhibited superior broadband nonlinear saturable absorption promising for nonlinear optical applications. Laser photolysis measurement implied that the nonlinear response origin was related to the long-lived electron-hole pairs delocalized within the BP QDs.
