Enhanced quantum dot emission for luminescent solar concentrators using plasmonic interaction

► The optical absorption of QDs/Au NPs composite enhanced. ► Transition in fluorescence, enhancement to quenching with Au NP concentration. ► The fluorescence enhancement due to modified excitation rate of QDs. ► Two distinctive states of QDs testified by double exponential decay lifetime. ► Competing factors, excitation rate, and quenching determine overall fluorescence.
