主　　题：photo-thermal conversion nanofluids Ag cesium tungsten oxide near-infrared 

摘      要：Nanofluids with full-spectrum absorption properties are highly desirable for direct solar thermal energy conversion *** this work,Ag and CsW03 nanofluids,which exhibit absorption both in the visible and near-infrared(NIR)region,are integrated to obtain twocomponent hybrid *** hybrid nanofluids show broad band absorption with a solar weighted absorption fraction of 99.6%,compared to 18%and 54%for the base liquid(ethylene glycol)and CsW03 nanofluids,*** highest photo-thermal conversion performance for the hybrid nanofluids is obtained with Ag/CsW03 weight ratio of 3/*** solar thermal conversion efficiency of the optimum hybrid nanofluids is 67%,10%and 15%higher than single Ag and CsW03 *** two-component hybrid nanofluid provides an alternative for making the best use of solar energy.
