CsPbX 3 Quantum Dots for Lighting and Displays: Room‐Temperature Synthesis, Photoluminescence Superiorities, Underlying Origins and White Light‐Emitting Diodes
Nanjing University of Science and Technology · Nanjing University of Aeronautics and Astronautics
Abstract
Recently, Kovalenko and co‐workers and Li and co‐workers developed CsPbX 3 (X = Cl, Br, I) inorganic perovskite quantum dots (IPQDs), which exhibited ultrahigh photoluminescence (PL) quantum yields (QYs), low‐threshold lasing, and multicolor electroluminescence. However, the usual synthesis needs high temperature, inert gas protection, and localized injection operation, which are severely against applications. Moreover, the so unexpectedly high QYs are very confusing. Here, for the first time, the IPQDs' room‐temperature (RT) synthesis, superior PL, underlying origins and potentials in lighting and displays are reported. The synthesis is designed according to supersaturated recrystallization (SR), which is…
