Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201502078-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Hydrogels are fabricated from CdSe/CdS seeded nanorod building blocks</bold> by the addition of hydrogen peroxide and converted to aerogels by supercritical drying. The aerogels show higher photoluminescence quantum yields and longer lifetimes than the hydrogels and the nanoparticle solutions. A model for this observation is derived. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgkv860h3v" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
