Abstract

<abstract abstract-type="graphical" xml:lang="en" id="advs201500194-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Emission color controlled, high quantum yield CH₃NH₃PbBr₃ perovskite quantum dots</bold> are obtained by changing the temperature of a bad solvent during synthesis. The products for temperatures between 0 and 60 °C have good spectral purity with narrow emission line widths of 28–36 nm, high absolute emission quantum yields of 74% to 93%, and short radiative lifetimes of 13–27 ns. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2n0t8gbw" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
