제목 Perovskite Nanoparticle Composite Films by Size-Exclusive Mass-Transfer Lithography
초록 Perovskite nanoparticle composite films have been fabricated by using size-exclusive mass-flow lithography (Scheme 1). Colloidal perovskites nanocrystals based on formamidinium lead halide (FAPbX3) have been synthesized by ligand assisted reprecipitation method using PbX2-DMSO complexes as precursors at room temperature. Well-defined cubic-shaped FAPbX3 nanocrystals have been obtained with a size of d = ~10 nm. The synthesized FAPbX3 nanocrystals show bright photoluminescence with a high photoluminescence quantum yield (PLQY for FAPbBr3 = 75%). The synthesized nanoparticles were composited with various polymers. With application of size-exclusive mass-flow induced by photo-polymerization, perovskite particles were assembled within the polymer matrix. By choosing the properties of monomers and kinetics of photo-polymerization process, the well-defined patterns of perovskite particles were prepared.
