“…The nanotube morphology obtained in this work agree with that obtained by Tong [8] for lead chalcogenide nanotubes synthesized by biomolecule-assisted self-assembly. It has been reported that PbSe having nanorods [16] and dendritic structure [17] can be prepared by hydrothermal method.…”

PbSe was prepared by hydrothermal method using 20, 60, 80, 100 mg contents of polyethylene glycol (PEG) as a surfactant. PbSe films with a thickness of about 120 nm and constant rate of evaporation were prepared on glass and quartz substrates using thermal evaporation technique for studying their electrical and optical properties, respectively. The prepared films were identified by X-ray diffraction, transmission electron microscope and energy dispersive X-rays. The variations of resistivity, carrier concentration and carrier mobility of the films with temperature and PEG content were investigated. The optical properties of the films were studied by using spectrophotometric measurements of the transmittance and reflectance in the wavelength range 500-2500 nm. The optical band gap of the films was calculated and it is found to increase with increasing PEG content.

In this paper, we report a preparation of CuZn dendritic microstructures through a tunable template-free electrochemical approach. By simply tunning the applied depositing current, the morphology of the product can be well controlled. The growth mechanism of CuZn dendritic alloys was also verified. The experimental results suggest that the growth of the grass-like structures obtained at 5 mA is driven by diffusion limited aggregation, while the driving force of the formation of CuZn dendrites obtained at 10 mA and 15 mA is gas bubbling worked as the dynamic template. The contact angle test shows the modified CuZn dendritic products possess superhydrophobic property. Additionally, through annealing of CuZn alloys in argon as the protective gas, derivative Cu/ZnO composite materials can be produced.

“…Deposition technique of chalcogenide materials was found recently controlling the deposited film properties. Many reports in lead selenide and its ternary compounds were deposited by chemical solution growth techniques [16][17][18][19][20][21], molecular beam epitaxy, MBE [22][23][24][25], electrochemical deposition [26], sol-gel technique [27], thermal evaporation [28,29], thermal reduction method [30], hydrothermal synthesis [31] and colloidal solution [32]. Each technique treats a specific problem such nano architecting, nano devices, wide area, ease preparation, nano particles and colloide, respectively.…”
