(a) Temporal evolution of the alcoholysis reaction of indium 2-ethylhexanoate. All spectra were normalized by the relatively intense C=C vibration band at 1641 cm−1 originating from ODE (the solvent) as the standard. (b) Temporal evolution of the normalized ester peak intensity, revealing that the reactivity of indium stearate is higher than that of indium 2-ethylhexanoate; (c) XRD patterns of the In3+ doped ZnO nanocrystals.
