Cadmium Selenide (CdSe) is a direct bandgap II-VI semiconductor material with excellent optoelectronic properties. It appears as a red or orange-red powder and is widely used in photodetectors, photovoltaic devices, quantum dots, and semiconductor applications. CdSe powder is available in high-purity grades (99.99% or higher), ensuring its suitability for advanced optical and electronic applications.

Key Properties

• Optical Properties: CdSe exhibits strong light absorption in the visible and infrared spectrum, making it an ideal material for optoelectronic applications.
• Electronic Properties: With a direct bandgap of approximately 1.7 eV (which can be tuned depending on particle size and synthesis methods), CdSe offers high photoresponsivity and efficient charge carrier transport.
• Thermal Stability: CdSe maintains good chemical and structural stability within a specific temperature range.
• Crystal Structure: It exists in either a cubic (zinc blende) or hexagonal (wurtzite) crystalline phase, each with distinct electronic and optical characteristics.

Applications

• Optoelectronic Materials: Used in photodetectors, solar cells, and light-emitting devices due to its excellent photoelectric response.
• Quantum Dot Technology: CdSe quantum dots are widely applied in LED displays, bio-imaging, fluorescence probes, and high-efficiency lasers.
• Semiconductor Industry: Serves as a crucial material for field-effect transistors (FETs), thin-film transistors (TFTs), and laser diodes.
• Sensors & Photocatalysis: CdSe-based materials demonstrate high sensitivity in gas sensors and strong photocatalytic activity for environmental applications.
