abstract = {This report presents a systematic study on the effect of
zinc (Zn) carboxylate precursor on the structural and
optical properties of red light emitting InP nanocrystals
(NCs). NC cores were assessed using X-ray photoelectron
spectroscopy (XPS), X-ray absorption spectroscopy (XAS),
energy-dispersive X-ray spectroscopy (EDX), and
high-resolution transmission electron microscopy (HRTEM).
When moderate Zn:In ratios in the reaction pot were used,
the incorporation of Zn in InP was insufficient to change
the crystal structure or band gap of the NCs, but
photoluminescence quantum yield (PLQY) increased
dramatically compared with pure InP NCs. Zn was found to
incorporate mostly in the phosphate layer on the NCs. PL,
PLQY, and time-resolved PL (TRPL) show that Zn carboxylates
added to the precursors during NC cores facilitate the
synthesis of high-quality InP NCs by suppressing
nonradiative and sub-band-gap recombination, and the effect
is visible also after a ZnS shell is grown on the cores.},
