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

CdTe CdS Core-Shell Nanoparticles

CdTe/CdS core-shell nanoparticles are a type of semiconductor quantum dot consisting of a cadmium telluride (CdTe) core and a cadmium sulfide (CdS) shell. These core-shell nanoparticles are widely used in nanotechnology, optoelectronics, and biomedical applications due to their excellent optical properties, high quantum efficiency, and tunable fluorescence.

Applications Biomedical and Biological Imaging

Fluorescent Imaging: CdTe/CdS quantum dots are used extensively in fluorescent imaging for cell tracking, molecular imaging, and in vivo imaging due to their bright fluorescence and long photostability. The size-tunable emission allows for the use of multicolor labeling in complex biological systems.

Biosensing: These quantum dots are used in biosensors for detecting specific biomolecules, such as proteins, DNA, and viruses. Their high quantum yield and bright fluorescence make them ideal for real-time detection in diagnostic applications.

Drug Delivery: Functionalized CdTe/CdS quantum dots can be used for targeted drug delivery, where their fluorescent properties allow for monitoring and tracking of therapeutic agents in the body. Their surface functionalization can be tailored to target specific cells or tissues, improving the efficacy and precision of drug delivery.

Optoelectronics

Quantum Dot Solar Cells (QDSCs): The ability of CdTe/CdS quantum dots to efficiently absorb light and convert it to electrical energy makes them suitable for use in quantum dot solar cells. The size-tunable optical properties of the quantum dots can be exploited to maximize light harvesting efficiency in solar energy applications.

Light-Emitting Diodes (LEDs): CdTe/CdS quantum dots are also used in quantum dot-based LEDs (QLEDs). Their tunable emission and high quantum yield make them attractive for applications in displays and lighting.
