Enhancing the Water Resistance and Stability of CsPbBr3 Perovskite Quantum Dots for Light-Emitting-Diode Applications through Encapsulation in Waterproof Polymethylsilsesquioxane Aerogels
Source abstract
Abstract
Highly stable all-inorganic perovskite quantum dot/polymethylsilsesquioxane aerogel (CsPbBr3/PMSQ AG) composites were first produced using two-step hot-injection and encapsulation processes by embedding green-emitting CsPbBr3 PQDs into modified hydrophobic mesoporous silica AGs. The unique structure of the composites not only considerably enhances the chemical stability of CsPbBr3 PQDs against moisture, humidity, and blue-light irradiation in air but also prevents anion exchange reactions during light-emitting diode (LED) manufacturing processes. In addition, the composition-optimized CsPbBr3/PMSQ AG exhibited excellent stability when soaked in water for more than 14 days and retained half of its initial intensity. Finally, white LED devices were fabricated by combining a blue-emitting GaN-based chip, green-emitting CsPbBr3/PMSQ AG, and red-emitting K2SiF6:Mn4+ phosphors.
