Room temperature synthesis of CsPbX3 (X = Cl, Br, I) perovskite quantum dots by water-induced surface crystallization of glass
Currently, the mainstream method for preparing perovskite quantum dots in glass is a heat treatment method. Here, a new method for the preparation of CsPbX3 (X = Cl, Br, I) quantum dots (QDs) by water-induced surface crystallization in tin fluorophosphates glass has been developed. A plausible water...

| description | Currently, the mainstream method for preparing perovskite quantum dots in glass is a heat treatment method. Here, a new method for the preparation of CsPbX3 (X = Cl, Br, I) quantum dots (QDs) by water-induced surface crystallization in tin fluorophosphates glass has been developed. A plausible water-induced surface crystallization mechanism has been proposed, revealing that water can reduce the non-uniform nucleation barrier to induce crystallization. Through changing the ratio of Cl/Br/I halogen elements in the raw material, a whole-family of CsPbX3 QDs in tin fluorophosphate glass can be obtained, covering the entire visible band from 414 nm to 713 nm. Besides, the proposed material technology may exert a vital role in the field of anti-counterfeiting technology shortly.
