Customizable Surface and Tunable Emission

Cadmium Sulphide and Zinc Sulphide Quantum Dots offer remarkable flexibility in surface functionalization, enabling linkage with amine, carboxyl, or PEG groups for tailored dispersibility. The particle size controls the emission wavelength, which can be adjusted from approximately 450 nm to 650 nm, making them ideal for specialized optical applications requiring precise color output.


High Quantum Yield and Stability

These quantum dots provide quantum yields of up to 80%, depending on synthesis quality and surface passivation. When stored under inert atmosphere in sealed vials, CdS and ZnS quantum dots demonstrate exceptional stability, ensuring reliability for long-term research and industrial use. Standard shelf life is 12-24 months under recommended conditions.


Advanced Synthesis Methods for Consistency

Utilizing colloidal and hot-injection techniques, the quantum dots are manufactured to exact specifications, ensuring consistent particle size, purity, and morphology. Their form, either as colloidal suspension or dry powder, meets technical and research grade standards for a broad range of applications.

FAQs of Cadmium Sulphide /Zinc Sulphide Quantum Dots:


Q: How are Cadmium Sulphide/Zinc Sulphide Quantum Dots synthesized?

A: Cadmium Sulphide and Zinc Sulphide Quantum Dots are typically produced using colloidal synthesis, particularly the hot-injection method, which allows precise control of particle size and uniformity for optimal optical properties.

Q: What applications benefit from using CdS/ZnS Quantum Dots?

A: These quantum dots are widely used in bio-imaging, LEDs, photovoltaic cells, sensors, lasers, and various optoelectronic devices due to their bright, tunable emission and high quantum yield.

Q: When should these quantum dots be stored or handled with extra caution?

A: Handling and storage should always be performed with care due to the toxic nature of heavy metals in CdS/ZnS Quantum Dots. Store in sealed vials under inert atmosphere, away from light and moisture, to maintain stability and safety.

Q: Where can these quantum dots be dispersed for different uses?

A: Depending on surface modification, CdS/ZnS Quantum Dots disperse well in aqueous or organic media, making them suitable for application-specific integration in research, manufacturing, and product development.

Q: What is the process for customizing the surface of these quantum dots?

A: Surface customization is achieved via functionalization with groups such as amine, carboxyl, or polyethylene glycol (PEG), which modifies the quantum dots solubility, compatibility, and dispersibility for targeted applications.

Q: How does particle size affect the color and emission wavelength of these quantum dots?

A: The emission wavelength and perceived color of the quantum dots are directly influenced by particle size. Modifying the size allows for emission tuning from yellow (~450 nm) to orange-red (~650 nm), offering precise control over optical output.

Q: What is the benefit of the high quantum yield in CdS/ZnS Quantum Dots?

A: A high quantum yield, up to 80%, ensures efficient light emission and signal strength in imaging, sensing, or display technologies, making these quantum dots powerful components in advanced photonic and electronic applications.
