摘要
-
All-inorganic perovskite quantum dots (PQDs) being characterized by high photoluminescence quantum yield, tunable emission colors and high color purity attract enormous attention in optoelectronic fields, especially as highly efficient narrow-band phosphors for lighting and next-generation display devices. However, poor stability seriously impedes their practical applications. Herein, we proposed an ion exchange/surface adsorption strategy to realize the room-temperature synthesis and stabilization of CsPbBr3 PQDs on alpha-Zr(HPO4)(2)center dot H2O (zirconium phosphate, alpha-ZrP) nanosheets. The inherent characteristics of the alpha-ZrP nanosheets including high Pb2+ adsorptivity and good Cs+ ion exchange capability promoted the heterogeneous nucleation-growth and effective anchoring of CsPbBr3 PQDs on alpha-ZrP surfaces. Consequently, the synthesized alpha-ZrP/CsPbBr3 composite exhibited superior green-emitting performance and significantly enhanced humidity stability and thermal stability in comparison to pure PQDs and many other matrix-protected PQDs. All these favorable characteristics listed above endowed the alpha-ZrP/CsPbBr3 composite with good optical properties for lighting and displays. This work opens up a new way to use inorganic nanomaterials to stabilize all-inorganic PQDs and can promote the scalable synthesis of PQDs with long-term stability for optoelectronic devices.
