Synthesis of location‐dependent phosphorus‐doped ZnO nanostructures on the porous alumina membranes

Abstract

Phosphorus-doped ZnO nanostructures are synthesized on porous alumina membranes by evaporating the mixture of pure Zn, carbon, and P 2 O 5 powder. The influences of growth area on phosphorus-doped ZnO nanostructures are studied in detail. The Raman spectra indicate that phosphorus enters into the ZnO crystal lattice to easily form a Zn-P bond and/or a P Zn -O one by occupying an O site and a Zn one. The further analyses for Raman spectra and SEM results display that the change of nanorods morphology should mainly be attributed to the relaxation of lattice strain caused by P occupying Zn sites. Compared with the morphology of samples on Si substrate, it is found that alumina membranes are helpful to the growth of nanostructures due to the existence of localized negative charges. The growth mechanism of different nanostructures is also discussed. The present research results are helpful to realize the preparation of phosphorus-doped ZnO nanostructures with controllable morphologies.

“…34 Besides, compared with ZnS, two new peaks at 354.9 and 477.1 cm −1 can be recognized in ZnS−BP nanosheets (Figure 3c), which are attributed to the Zn−P bond based on the literature reports. 33,35 In addition, as shown in the P 2p XPS spectra in Figure 3d, compared with ZnS, a new peak located at ∼140 eV is found in ZnS−BP nanosheets, corresponding to the Zn−P bond according to the literature report. 35 Consequently, combining the DFT calculation and experimental characterization, it is confirmed that a certain Zn−P bond is built in ZnS−BP nanosheets.…”

The construction of the Zn−P bond can not only improve the stability of BP NPs but also improve the carrier transport performance and hydrogen adsorption−desorption equilibrium of ZnS−BP nanosheets.…”
