Abstract

<abstract abstract-type="graphical" xml:lang="en" id="smll201470041-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A novel way to tune the bandgap in an Ag₂S quantum dot (QD) system is developed by inducing a lattice‐distorted region of ≈1‐nm scale in a QD with rapid quenching. Accordingly, the bandgap can be controlled simply by tailoring the degree of the lattice‐distortion in a QD (2.51 to 1.64 eV). As reported by H. M. Jang and co‐workers on page 1300, this conceptual method can pave a new way to realize quantum effects in future QD‐based applications. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg52x8svzq" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
