Perovskite Quantum Dots: Enhancing the Stability of Perovskite Quantum Dots by Encapsulation in Crosslinked Polystyrene Beads via a Swelling–Shrinking Strategy toward Superior Water Resistance (Adv. Funct. Mater. 39/2017)

In article 1703535, Ziyong Cheng, Jun Lin, and co-workers present a method to stabilize perovskite quantum dots (PQDs). Highly luminescent perovskite–polystyrene composite beads with uniform morphology are prepared by packing perovskite quantum dots in crosslinked polystyrene beads via swelling in toluene and then shrinking the beads in hexane. The composite preserves optical performance even being immersed into water over nine months.
