Synthesis, Structural and Optical Investigation of CdSe semiconductor Quantum Dots

Biomass‐derived Carbon Quantum Dots – A Review. Part 1: Preparation and Characterization

“…(2008) used a microwave method for the synthesis of water‐dispersed CdTe/CdS/ZnS core‐shell‐shell semiconducting quantum dots of the size 4.5 nm 6. CdSe semiconductor quantum dots are prepared by a chemical method at room temperature with an average particle diameter of 2.5 nm 7. CdS QDs‐decorated ZrO 2 used as photoanode in sensitized solar cells which exhibit easy transition of injection of electrons between the conduction band edge of photoanode (ZrO 2 ) and the conduction band edge of sensitizers or window materials (CdS QDs) due to conduction band edge of ZrO 2 has almost at the same level of the conduction band of CdS QDs 8.…”

“…This strategy is modeled on the basis of heating at reflux the ionic precursors (generally, metal acetate, nitrate, sulfate, chlorate or perchlorate) with S 2precursor (NaS2) in an inert ambience and the presence of different types of stabilizing agents, such as, 1thioglycerol [47], glutathione (GSH) [7], [45], 3-mercaptopropionic acid (3-MPA) [21], [48], mercaptoacetic acid (MAA), mercaptosuccinic acid (MSA) [48], dithiothreitol (DTT), thioglycolic acid (TGA) [23], [48], thiolactic acid (TLA) [48], 2-mercaptoethylamine (2-MEA), cysteine [44], 2-mercaptoethanol [47], 1-mercapto-2-propanol, 2-dimercapto-3-propanol [6], dihydrolipidic acid (DHLA) etc [49]. The photoluminescence QYs of the QDs prepared by this approach is strictly relied upon varying the experimental conditions, such as pH of the medium, precursor concentration, temperature, and refluxing time [50], [51].…”
