  "abstract": "Surface chemistry governs the optical performance of InP quantum dots (QDs), but strategies for preparing highly emissive InP/ZnS materials often rely on hazardous fluoride treatments. Here, treatment of carboxylate-capped InP QDs with PCl3 before ZnS shell growth increases the photoluminescence quantum yield from 5.5% to 70% without HF. 31P NMR spectroscopy and time-resolved small angle neutron scattering show that PCl3 removes surface carboxylates through formation of tricarboxyphosphite species. PCl3 treatment alone does not enhance emission, demonstrating that surface modification instead enables more effective passivation during shelling. These results establish controlled ligand stripping as an HF-free strategy for engineering the InP/ZnS interface and reveal how surface coordination can modulate the electronic structure and subsequent passivation of InP nanocrystals.",
