Cadmium Sulfide Nanoparticles / CdS Nanopowder (99.5%, 5nm)

Cadmium Sulfide Nanoparticles/CdS Nanopowder Application:

Cadmium Sulfide Nanoparticles represents an important area of research due to their applications in biology, medicine, engineering, energy storage and production, etc. The properties of functionalized materials can be superior to those of the pristine ones, and new applications were found based on their properties.

Photovoltaic Devices and Solar Cells

CdS nanoparticles are extensively studied in photovoltaic devices, especially as buffer layers in thin-film solar cells (such as CdTe solar cells). CdS, with its bandgap of around 2.4 eV, is ideal for absorbing visible light and converting it into electricity. It plays a crucial role in enhancing the efficiency of solar cells by increasing the light absorption and improving the overall performance of the device.

CdS nanoparticles are also used in quantum dot solar cells, where their size-dependent optical properties enable efficient light harvesting and energy conversion.

Quantum Dots for Optoelectronics

CdS nanoparticles, when synthesized as quantum dots, exhibit tunable optical properties, including photoluminescence (PL) and fluorescence. These properties make them suitable for use in light-emitting diodes (LEDs), lasers, and displays.

In quantum dot LEDs (QLEDs), CdS nanoparticles emit bright, tunable light when electrically stimulated, making them promising for next-generation display technologies such as high-resolution screens, televisions, and projectors.

Fluorescent Imaging and Biological Labeling

CdS nanoparticles are widely used in biological imaging due to their bright fluorescence and quantum size effects. These nanoparticles can be functionalized with biomolecules to target specific cells or tissues, enabling cellular imaging and molecular diagnostics.

Fluorescence-based bio-labeling allows for non-invasive tracking of biological molecules, making CdS NPs valuable in biomedical research and clinical diagnostics for detecting diseases like cancer or monitoring drug delivery.
