Optoelectronics: Enhanced Stability and Tunable Photoluminescence in Perovskite CsPbX₃ /ZnS Quantum Dot Heterostructure (Small 21/2017)

A novel architecture made of a CsPbX3/ZnS quantum dot heterostructure is reported, by Xiaosheng Tang, Miao Zhou, and co-workers in article number 1604085, by combining material synthesis, characterization, optical measurements and density functional theory based first-principles calculations. This architecture presents high crystal quality, enhanced structural stability and tunable optoelectronic properties, providing an exciting playground for future exploration of novel and high-performance optoelectronic devices.
