“…Morphology-controlled synthesis of nano-/micro-crystals of semiconductor materials have attracted great interest because their optoelectronic properties are closely related to their sizes and shapes [1][2][3][4][5][6][7][8]. Compared to mono-morphological structures, hierarchical structures may show unique properties by combining the features of micrometer-and nanometer-scaled building blocks in one crystal [9][10][11].…”

“…In the FT-IR spectrum of diphenylthiocarbazone (Figure 2(b), curve a), the absorption peaks at 3445, 2962, 1594 and 1499, 1438, 1221, 1145, 888, 679, and 752 cm −1 correspond to the stretching vibration mode of N-H band, methylene C-H asymmetric vibration band, benzene ring stretching band, C=S stretching mode, deformation vibration of N-H band, C-H inplane bending vibration of benzene ring, N-N stretching mode, and benzene ring deformation vibration mode, respectively [33]. As shown in Figure 2(b) (curves bg), the peaks belonging to diphenylthiocarbazone disappeare, only leaving one strong broad peak at 3451 cm −1 corresponding to the O-H stretching vibration of water [34].…”

A simple and facile approach was developed in the solvothermal synthesis of hierarchical PbS microstars with multidendritic arms, which were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) and photoluminescence (PL) spectroscopy. The morphologies of PbS products were strongly determined by the reaction time and temperature, the ratios of the precursors, and the mixed solvent with various components, and thereby their possible formation mechanism was discussed in some detail. The as-prepared PbS crystals displayed a sharp and strong photoluminescent peak at 437 nm at room temperature. It has potential and practical applications in photoluminescence, photovoltaics, IR photodetectors, electroluminescence, and solar absorbers.

“…Hence, the growth direction of the grown CdS NWs is along 001 . The (002) peak intensity is higher than those of the (100) and (101) planes of the CdS NWs grown at 160 • C for 3•5 h, which may be due to the lower aspect ratio (Zhou et al 2011). Growth along the c-axis of the NW wurtzite structure benefits optoelectronic and electro-optic applications due to the polarized light emission along the c-axis of the wire (Thupakula et al 2012).…”

Cadmium sulfide (CdS) nanowires (NWs) were prepared by the solvothermal method using ethylenediamine as a solvent. Two sets of CdS NWs were synthesized at 160 and 200 • C for various reaction durations (3•5, 7 and 24 h). Scanning/tunneling electron microscopy was used to examine the surface morphology of the grown NWs. Their dimensions are found to depend on the reaction temperature and duration. The CdS NWs grown at 200 • C for all durations are longer than those prepared at 160 • C, with diameters ranging from 15 to 40 nm. A threearmed structure is exhibited by all the samples. The grown CdS NWs display a hexagonal wurtzite phase and grows along the 001 direction. The optical absorption of the grown NWs shows a sharp absorption edge with a blueshift, which indicates an expansion of the optical band gap. All prepared samples show two emission peaks in their photoluminescence spectra. The emission peak location depends on the reaction temperature and duration. The CdS NWs prepared at 160 • C show a sharp band-band emission compared with those prepared at 200 • C. Raman analysis indicates that the optical properties of the grown NWs are enhanced with increased temperature and reaction duration.
