A novel method for PbS quantum dot synthesis

Enhanced charge collection and photocatalysis performance of CdS and PbS nanoclusters co-sensitized TiO2 porous film

“…The SILAR technique [17][18][19] was employed to assemble CdS and PbS nanoclusters on TiO 2 porous films. Briefly, the TiO 2 porous film was dipped into 0.5 M cadmium acetate solution for 5 min and thoroughly rinsed with DI water, then dipped into 0.5 M sodium sulfide solution for another 5 min and rinsed with DI water.…”

X-ray diffraction line profile analysis of chemically synthesized lead sulphide nanocrystals

“…In recent years, nanostructured materials have been the subject of intensive scientific and technological interest because of their novel optical, electrical, magnetic and mechanical properties [1,2]. Lead sulphide (PbS) is a group IV-VI semiconductor with a direct bandgap of 0.41 eV (in bulk form) and a large exciton Bohr radius of 18 nm [3], making bandgap tuning possible over a wide range of crystallite sizes.…”

Synthesis of Water-Soluble Antimony Sulfide Quantum Dots and Their Photoelectric Properties

“…At the early stage of this reaction, the solution containing equimolar SDS/CTAB tended to form relatively larger catanionic vesicles rather than mixed micelles [16]. The reaction between S 2− and Sb 2+ took place rapidly, leading to the explosive nucleation.…”

“…In order to overcome the interference of hydroxyl, the reaction was conducted in anhydrous 2-methoxyethanol instead of water. These precursors are nontoxic, odorless, and inexpensive compared with conventional additives [16, 17]. Before the substantial application, the structural, optical, and electrical properties were studied herein.…”
