Spectroscopic characterization of InP and InP/ZnS QDs. a Absorption spectra of different InP and InP/ZnS (15 min) QDs in hexane. b PL spectra of different InP/ZnS (15 min) QDs in hexane. c Absorption spectra and PL spectra before and after ligand exchange for InP/ZnS QDs (525 nm, 15 min) in hexane and water (the absorbance of the two QD types was adjusted to the same value at the excitation wavelength to enable PL comparison). d FT-IR spectra of QDs before and after ligand exchange
