CdS/Ag2S Core Shell Nanoparticles (Cadmium Sulphide/Silver Sulfide, 99.9%, APS: 80-100nm, Inorganic Semiconductor)

CdS/Ag2S Core-Shell Nanoparticles

 Cds/ ag2s core-shell nanoparticles are a class of nanomaterials that combine the unique properties of cadmium sulfide (CdS) and silver sulfide (Ag2_22​S), both of which are semiconductor materials. These nanoparticles consist of a CdS core surrounded by a Ag2_22​S shell, and the combination of these two materials imparts enhanced optical, electronic, and catalytic properties, making them highly useful in a variety of applications.

Applications

Photocatalysis

Solar Energy Conversion: The CdS/Ag2_22​S core-shell nanoparticles can be used in photocatalytic applications, such as solar hydrogen production and water splitting. The enhanced light absorption across a broader spectrum, including UV, visible, and near-infrared light, makes these nanoparticles suitable for solar-to-hydrogen conversion and solar energy harvesting.

Pollutant Degradation: CdS/Ag2_22​S nanoparticles are efficient at degrading organic pollutants, such as dyes, pesticides, and industrial waste products, when exposed to UV or visible light. This makes them ideal for use in environmental remediation and wastewater treatment applications.

Biosensing and Bioimaging

Fluorescence and Sensing: The luminescent properties of CdS combined with the infrared absorption characteristics of Ag2_22​S allow CdS/Ag2_22​S nanoparticles to be used as fluorescent probes for biosensing and bioimaging. These nanoparticles can be functionalized with biomolecules to detect specific diseases, tumors, or pathogens in biological samples.

Bioimaging: The strong fluorescence of CdS and the broad absorption properties of Ag2_22​S make these nanoparticles useful for in vivo and ex vivo imaging in biological systems.

Antibacterial and Antifungal Applications

Antimicrobial Coatings: The antibacterial properties of Ag2_22​S make these nanoparticles suitable for use in antimicrobial coatings. They can be applied to surfaces such as medical devices, wound dressings, and water filtration systems to prevent microbial growth.

Water Purification: CdS/Ag2_22​S core-shell nanoparticles are also being explored for use in water purification due to their antibacterial properties and photocatalytic degradation of contaminants in water.

Infrared Photodetectors

Night-Vision Devices: The narrow bandgap of Ag2_22​S allows the CdS/Ag2_22​S nanoparticles to absorb infrared light, making them ideal for use in infrared photodetectors and night-vision systems. These nanoparticles can be incorporated into thermal cameras and optical sensors to detect infrared radiation in the mid-IR and long-wavelength regions.
