1) When metal nanoparticles are excited by light, they exhibit localized surface plasmon resonance (LSPR) which enhances the local electric field. This study investigates how gold nanoparticles with silica shells of different thicknesses influence the photoluminescence of nearby quantum dots (QDs). 2) Time-resolved fluorescence and photon correlation measurements show that QDs near gold nanoparticles with thinner silica shells have higher biexciton emission quantum yields compared to QDs on glass. 3) Electrodynamics modeling suggests that the enhanced local electric field and additional non-radiative energy transfer from QDs to gold nanoparticles impact exciton and biexciton emission intensities and lifetimes in a way that increases the bi
