Controlled Solvothermal Synthesis of Nanosheets, Nanobelts, and Ultralong Nanobelt Arrays with Honeycomb-Like Micropatterns of ZnSe on Zinc Substrate

Abstract: Nanosheets, nanobelts, and ultralong nanobelt arrays with honeycomb-like micropatterns of ZnSe were synthesized via a solvothermal reaction of Zn with Se and KBH(4) in ethylenediamine at 200 degrees C for 24 h and subsequent annealing. The control over these nanostructures with different morphologies was achieved by adjusting the KBH(4)/Se molar ratio. The role of KBH(4) in the formation of ZnSe(en)(0.5) nanobelts with different length-to-width ratios was investigated, and a possible mechanism was also propose… Show more

“…4 are assigned to the asymmetric and the symmetric stretching vibrations of -NH 2 , respectively, while the lines at 1600 and 1030 cm −1 are attributed to the scissoring and wagging vibrations of -NH 2 , respectively. 27 The absorption peaks at 2934, 2869, and 1355 cm −1 correspond to the asymmetric and symmetric stretching and wagging vibrations of -CH 2 , respectively, and the absorption peaks at 1086 cm −1 can be assigned to the C-N stretching vibration. 27 The FTIR spectra of nanostructures grown at various temperatures in Fig.…”

“…And ZnS(en) 0.5 has two preferential growth directions, <0001> and <01true1¯0> . BH4 adsorbs on Zn planes perpendicular to <01true1¯0> direction of ZnS(en) 0.5 nuclei . Therefore, the growth of ZnS(en) 0.5 crystal along <01true1¯0> direction is suppressed effectively .…”
