<description xml:lang='en' descriptionType='Abstract'><p>In this study, Ag-doped ZnO (ZnO:Ag) nanostructured films were functionalized with silver nanoparticles (Ag NPs), silver-platinum bimetallic nanoparticles (AgPt NPs) and silver-gold bimetallic NPs (AgAu NPs) using a gas phase PVD process based on a Haberland type gas aggregation cluster source and unipolar DC planar magnetron sputtering. Ultraviolet (UV) sensing investigations showed a respectable time constants reduction for rising and decaying photocurrents, as well as an increase for the UV response. Compared to a pristine nanostructured film the surface functionalization with Ag, AgPt and AgAu increased the UV response by factors of 2.7, 3.5 and 4, respectively. The increased performances of the here presented ZnO:Ag nanostructured films functionalized with monometallic and bimetallic NPs based photodetectors are explained by the increased lifetime of photogenerated electron &ndash; hole pairs, as well as the formation of nanoscale Schottky barriers at the interface of Au/ZnO:Ag and Pt/ZnO:Ag.</p></description>
<description xml:lang='ro' descriptionType='Abstract'><p>&Icirc;n acest studiu, filmele nanostructurate ZnO (ZnO: Ag) au fost funcționalizate cu nanoparticule de argint (Ag NPs), nanoparticule bimetalice argint-platină (AgPt NPs) și NPuri bimetalice de aur (AgAu NPs) folosind o sursă cluster de agregare de gaz tip Haberland și un pulverizator unipolar planetar magnetron plan. Analiza sensibilității ultraviolete (UV) a arătat o reducere a constantelor de timp pentru fotocurenturile &icirc;n creștere și degradare, precum și o creștere a răspunsului UV. Comparativ cu un film nanostructurat fără adaosuri, funcționalitatea suprafeței cu Ag, AgPt și AgAu a crescut răspunsul UV cu factori de 2,7; 3,5 și respectiv 4. Performanțele majorate ale filmelor nanostructurate ZnO:Ag, funcționalizate cu fotodetectoare bazate pe NP monometalice și bimetalice se explică prin creșterea duratei de viață a perechilor fotogenerate de electroni, precum și prin formarea barierelor Schottky de scară nanometrică la interfața Au / ZnO: Ag și Pt / ZnO: Ag.</p></description>
