Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Inorganic nanostructures</bold>: Alloyed Cu₂ZnSn(S_{1−<italic>x</italic>}Se_{<italic>x</italic>})₄ wurtzite nanocrystals (10 nm in size) with a varying composition (<italic>x</italic>=0–1) were synthesized using a colloidal hot injection route. A photoluminescence (PL) emission study of these nanocrystals shows a compositionally tunable band‐gap ranging between 0.9–1.4 eV that directly correlates to the sulfur‐to‐selenium ratio (see picture).<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg36jzxmvm" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
