Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adom201300530-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A fullerene‐based nanocomposite photodetector</bold> with peak quantum efficiency over 400% and specific detectivity of 6.5 × 10¹² Jones at a wavelength of 390 nm is enabled by a cross‐linked polymer:ZnO nanocomposite buffer layer. The introduced ZnO nanoparticles not only increase the photoconductive gain through a trap‐controlled electron injection mechanism, but also effectively reduce the noise current, yielding a record linear dynamic range (LDR) of 120 dB. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg59w0w3p1" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
