Controllable Growth of Ultrathin P-doped ZnO Nanosheets

Abstract

Ultrathin phosphor (P)-doped ZnO nanosheets with branched nanowires were controllably synthesized, and the effects of oxygen and phosphor doping on the structural and optical properties were systematically studied. The grown ZnO nanosheet exhibits an ultrathin nanoribbon backbone with one-side-aligned nanoteeth. For the growth of ultrathin ZnO nanosheets, both oxygen flow rate and P doping are essential, by which the morphologies and microstructures can be finely tuned. P doping induces strain relaxation to change the growth direction of ZnO nanoribbons, and oxygen flow rate promotes the high supersaturation degree to facilitate the growth of nanoteeth and widens the nanoribbons. The growth of P-doped ZnO in this work provides a new progress towards the rational control of the morphologies for ZnO nanostructures.

“…S6, supplementary material). 17,22 It can be explained that O vacancies or Zn interstitials introduce impurity states in the forbidden band as observed in PL characterization and absorption characterization (see Fig. S7, supplementary material).…”

P-type α-Fe2O3 hexagonal nanosheets: Synthesis and aniline-sensing performance

“…We can see a broad emission peak near 570 nm and mark it in the spectrum, which may be related to the oxygen vacancy defect of Fe 2 O 3 . 35,36 The synthesis process may introduce oxygen vacancies which play a crucial role in changing the P-N type of the sample.…”

Strain engineering of two-dimensional materials for energy storage and conversion applications

“…The relaxation of strain at the periphery was easier than that in the inner region, resulting in a long-range strain field extending from the edge to the center [Figure 2F and G]. Moreover, doping-induced strain can also be observed in PdIr bimetallene [65] , ZnO nanosheets [66] , and nickel hydroxide nanosheets [67] .…”
