【 摘 要 】

All inorganic perovskite quantum dots have excellent luminous properties such as high quantum efficiency, broad luminescence spectrum and narrow emission peak, which have potential applications in the field of photovoltaic and light emitting devices. All inorganic perovskite CsPbBr1.5I1.5 quantum dots were prepared by an ion exchange method based on the traditional hot injection method. The luminescence and structure properties were tested, and we found that this method can get different light emitting position by adjusting the content of Br or I, and the structure of inorganic perovskite would not be changed.
