Figure 2. P 2p XPS spectra of (A) pristine InP and InP-Zn(OA)2 cores; (B) a series of InP-ZnX2 cores; and (C) a series of InP-ZnX2-Zn(OA)2 cores; (D) 31P NMR spectra of InP-Zn(OA)2 and a series of InP-ZnX2-Zn(OA)2 cores; Photographs of a set of (E) InP-ZnX2 and (F) InP-ZnX2-Zn(OA)2 cores under UV irradiation. XPS: X-ray photoelectron spectroscopic; InP: indium phosphide; NMR: nuclear magnetic resonance; UV: ultraviolet.
