Synthesis of star-shaped PbS nanocrystals using single-source precursor

Improved magnetism in Cr doped ZnS nanoparticles with nitrogen co-doping synthesized using chemical co-precipitation technique

“…The observed increase in the band gap energy when the semiconductor crystal size is in the nanometer range can be attributed to the quantum confinement effect [1][2][3][4]. Chemical doping is a fascinating way to intrinsically modify the physical and chemical properties of semiconductor nanostructures.…”

CuS nanostructures prepared by a hydrothermal method

“…In recent years, materials with three-dimensional (3D) architectures have attracted much attention due to their structural complexities, novel or improved properties, and wide potential applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Among these 3D architectures materials, semiconducting metal sulfides, such as In 2 S 3 , CdS, SnS, Bi 2 S 3 , PbS and CuS, have been widely studied, owing to their excellent physical and chemical properties [1][2][3][4][5][6][7][8][9][10][11][12].…”

For instance, Liu et al have prepared 3D flowerlike architectures of ␤-In 2 S 3 assembled with nanoflakes using thiosalicylic acid and carbon disulfide as the double sulfur sources via a one-step solvothermal route [1].…”

“…Jiang et al have synthesized uniform chrysanthemum-like Bi 2 S 3 microcrystals assembled from nanosheet building blocks via a convenient hydrothermal synthetic route employing hydrated bismuth nitrate and l-cysteine [2]. Salavati-Niasari et al have prepared star-shaped PbS nanocrystals using single-source precursor and SnS nanoflowers in the presence of thioglycolic acid via a simple hydrothermal method [8,9].…”

Fe:ZnSe semiconductor nanocrystals: Synthesis, surface capping, and optical properties

“…Colloidal semiconductor nanocrystals (NCs) have currently been attracting widespread scientific and technological interest due to their unique size-tunable optical and electronic properties as well as their potential applications in solar cells, light-emitting diodes (LEDs) and bio-labels [1][2][3][4][5][6][7][8][9][10][11][12], etc. However, the small ensemble stokes shifts of intrinsic NCs emitters make self-quenching, that is a serious issue if the fluorescent labels must either be kept close to, or be in, a high absorbance [13].…”
