Abstract

Photoluminescence tunability is exceedingly crucial to all-inorganic halide perovskite (CsPbX 3, X = Cl, Br, I) quantum dots (QDs) for high-resolution display. However, up to now, the wide-range color tunability could only be achieved by varying the halide ratio. A drawback in this approach is the c...
