Polymer encapsulation shields perovskite nanocrystals from degradation

Wed, 08/07/2019 - 10:15
Due to their fascinating optoelectronic properties, halide perovskites have attracted tremendous research interest as promising materials for photovoltaics, photodetectors, LEDs, and lasers. Researchers report report a strategy to synthesize perovskite nanocrystals using diblock copolymer micelles as a growth template. This work constitutes a new approach for synthesizing perovskite nanocrystals of controllable size and composition with vastly improved resistance to halide ion migration and environmentally induced degradation.
