研究了高结晶度CsPb（Br/I）（3）钙钛矿量子点的非线性光学性质。钙钛矿量子点比传统的金属硫族化合物量子点具有更好的双光子吸收响应。首次在实验上观察到了钙钛矿纳米晶中卤素空位的光致发光峰。
We present the nonlinear optical properties of CsPb(Br/I)(3) perovskite quantum dots (QDs) with high crystallinity. The perovskite QDs show better two-photon absorption response than the traditional metal chalcogenide QDs. And, the photoluminescence peak of the halogen vacancies in perovskite nanocrystals was experimentally observed for the first time.
