The emission energy of the excited CdSe quantum dot near the silver nanowire could couple to guided surface plasmons in the
nanowire . Especially, in the optical properties, this type of nanocomposite has attracted this website great scientific interest . It is just the complexity of the interaction; different factors, including composition, size, and geometry of the nanostructures; and the distance between nanostructures that provide the challenge for quantifiable research and the mechanism achievement of a new phenomenon . So, the preparation and synthesis of uniform nanomaterials in terms of morphology and structure provide the important precondition for the further study of material properties. As a narrow bandgap semiconductor (approximately 0.32 eV, at 300 K), lead telluride (PbTe) has been extensively studied and used in optical detectors , laser devices [14, 15], and thermoelectrics [16, 17]. Compared to other semiconductor materials, low-dimensional PbTe semiconductors could more A-1210477 datasheet easily show the obvious quantum size effect on larger scales because of the larger Bohr exciton radius (approximately 46 nm). So, 1D PbTe nanomaterials have attracted intense scientific attention in recent years and have been synthesized by a variety of physical and chemical techniques [16–22].
The solution-based chemical synthesis and chemical vapor selleck chemicals llc deposition have been usually utilized to synthesize single-crystalline PbTe nanowires, and the conventional electrical property measurement of PbTe nanowires has been achieved [16, 23]. However, less attention has been paid to the preparation and unique property
study of 1D PbTe-based nanocomposites at present. In this paper, we first electrodeposited the nanostructure arrays made of a uniform PbTe/Pb nanostructure in size and composition. Then, the regular PbTe/Pb nanostructure arrays and the synthesized Zn x Mn1−x S nanoparticles were assembled to construct a PbTe-based nanocomposite. The photoelectric property measurements of the material were also performed in situ along with the assembly process of the nanocomposite. The measurement results showed that the photoelectric performance of the PbTe/Pb-based nanocomposite had an obvious improvement compared to that of the individual PbTe/Pb nanomaterial. The improved performance of the nanocomposite could originate from the synergistic effect brought by the incident light Inositol monophosphatase 1 and exciting light of the nanoparticles. The underlying mechanism shows that the light-use efficiency (LUE) of the PbTe/Pb-based nanocomposite had an obvious increase compared to that of the PbTe/Pb nanomaterial. Methods Synthesis of nanostructure arrays by electrodeposition In our experiments, the regular PbTe/Pb nanostructure arrays were electrodeposited on a silicon (110) wafer. The electrodeposition process was achieved in a few hundred-nanometer- thick electrolyte layer, which was controlled with an ultrathin electrochemical deposition setup .
