Shape controlled synthesis of PbS nanocrystals by a solvothermal–microemulsion approach

Characterization of PbS nanoparticles synthesized by chemical bath deposition

“…Moreover, an exceptional thirdordered nonlinear optical property of PbS nanoparticles has been found, and it is predicted that as compared with GaAs or CdS with a given particle size, the nonlinear properties of PbS are the best [12]. The absorption edge of PbS exhibits a large blue shift [13] when one shrinks the crystallite size to the nanometer size regime. Thus, extensive work about its preparation and properties are being implemented.…”

Fabrication of PbS microstructures with different shapes in aqueous solutions of amphiphilic triblock copolymer

“…Especially, shape control of chalcogenide semiconductor materials has attracted great attention because of their unique electronic, optical properties, as well as important applications in single-electron transistor, nonlinear optics [10][11][12]. PbS is an important semiconductor with a rather small bulk band gap (0.41 eV at 300 K) and a relatively large excitation Bohr radius (18 nm) [13], and has wide applications in Pb 2+ -selective sensors [14], photography [15], near-IR detectors [16], and solar absorbers [17].…”

A new route to fabricate PbS nanofibers and PbSe nanofibers via electrospinning combined with double-crucible technique

“…Typical synthetic methods include hydrothermal-solvothermal synthesis method [7,8], coprecipitation [9], microemulsion [10], pyrolysis [11,12], solid state reaction [13], ultrasonic assisted route [14], microwave synthesis [15], etc. Different morphological PbS and PbSe nanomaterials were prepared by the above methods, including nanocrystals [16][17][18], nanocubes [19], nanowires [20], nanorods [21], nanoparticles [22], nanospheres [23], etc.…”
