“…The observed peaks can be attributed to the presence of Zn atoms as Zn 2+ on the surface of the material. 54,55 Thus, Zn atoms might replace some of the Cd atoms in the CdSe structure and form a Zn-Se bond. , which has been shown to signicantly increase the amount of hydrogen production at the cathode.…”

This study reports the synthesis of Zn x Cd 1Àx Se quantum dot-sensitized titania nanotube array photoelectrodes using a successive ionic layer adsorption and reaction technique and evaluates the photoelectrochemical performance as anodes. The effect of altering the number of sensitization cycles and annealing temperature on optical and photoelectrochemical properties of prepared photoanodes was studied. Surface morphology of the sensitized tubes was analyzed by scanning electron microscopy, while the phase composition was determined using X-ray diffraction and X-ray photoelectron spectroscopy techniques. Spectral response measurements indicated that TiO 2 nanotube arrays coupled with Zn x Cd 1Àx Se quantum dots synthesized in 7 cycles of deposition and annealed at 300 C for 1 h under N 2 exhibited excellent photoelectrochemical properties. The notably high photovoltaic characteristics demonstrate the potential of the Zn x Cd 1Àx Se/TiO 2 heterostructure as an efficient photoanode.

“…ZnSe nanostructures have been achieved by several methods, such as thermochemical method [8], atomic layer deposition method [11], solvothermal processes [12], and hydrothermal method [13]. In hydrothermal and solvothermal processes, the morphology of the as-grown samples can be easily influenced by some additives such as ethylene diamine tetraacetic acid (EDTA) [14], diethanolamine [15], and hydrazine hydrate (N 2 H 4 Á 2H 2 O) [16].…”

“…It is a common material used in optoelectronic applications such asphotovoltaic devices, light-emitting devices, transmission windows, and storage devices, as well as in Lasik surgery [2,3]. ZnSe can be synthesized using various methods such as the sol-gel, thermal evaporation, wet chemical synthesis, hydrothermal and solvothermal methods [4,5,6,7,8]. The shape and size of ZnSe are easily controlled using the hydrothermal or solvothermal method.…”

The effect of NaOH solution on the formation of nanoparticles has been the subject of ongoing debate in selenium-based material research. In this project, the robust correlation between the mechanistic growth of zinc selenide/graphene oxide (ZnSe/GO) composite and the concentration of NaOH are elucidated. The ZnSe/GO composite was synthesized via microwave-assisted hydrothermal method and the concentrations of NaOH are controlled at 2 M, 3 M, 4 M, 5 M and 6 M. The XRD spectra show that the crystal phases of the samples exhibited a 100% purity of ZnSe when the concentration of sodium hydroxide (NaOH) was set at 4 M. The further increase of NaOH concentration leads to the formation of impurities. This result reflects the essential role of hydroxyl ions in modifying the purity state of ZnSe/GO composite. The optical band gap energy of ZnSe/GO composite also decreased from 2.68 eV to 2.64 eV when the concentration of NaOH increased from 2 M to 4 M. Therefore, it can be concluded that the optimum concentration of NaOH used in synthesizing ZnSe/GO composite is 4 M. This project provides an alternative green method in the formation of a high purity ZnSe/GO composite.
