Cadmium Selenide CdSe Sputtering Targets 

High-purity cadmium selenide (CdSe) sputtering targets (99.99% purity) are critical for advanced thin-film deposition in PVD (magnetron sputtering) 

and thermal evaporation systems. As a direct bandgap semiconductor (~1.74 eV), CdSe offers exceptional optoelectronic tunability, 

making it indispensable for next-generation research in academia and industry. Below are its key applications:

1. Optoelectronics & Photovoltaics

Quantum Dot Synthesis: CdSe thin films serve as precursors for high-efficiency CdSe/CdS core-shell quantum dots, widely used in displays, LEDs, 

and biological imaging.

Solar Cells: Integration into CIGS (CuInGaSe₂) thin-film solar cells as buffer layers or absorbers to enhance light-harvesting efficiency.

Photodetectors: Fabrication of visible-to-near-infrared (Vis-NIR) photodetectors for optical communication and sensing systems.

2. Nanoelectronics & Quantum Technologies

2D Heterostructures: Deposition of CdSe layers for hybrid structures with graphene, MoS₂, or perovskites to study charge transfer mechanisms.

Single-Photon Emitters: Development of nanoscale CdSe-based emitters for quantum cryptography and quantum computing research.

3. Infrared Optics & Coatings

IR Transparent Films: CdSe’s broad infrared transmission range (up to ~25 µm) enables coatings for thermal imaging lenses and IR sensor windows.

Anti-Reflective Coatings: Multi-layer designs for laser optics and aerospace-grade infrared systems.

4. Energy Conversion & Catalysis

Photoelectrochemical Water Splitting: CdSe films act as photocathodes for hydrogen generation studies due to their favorable band alignment.

CO₂ Reduction Catalysts: Thin-film electrodes for converting CO₂ into hydrocarbons under visible-light irradiation.

5. Biomedical & Sensor Applications

Bioimaging Probes: CdSe nanoparticles synthesized via thin-film precursors for fluorescent labeling in cellular imaging.

Gas Sensors: CdSe-based resistive sensors for detecting volatile organic compounds (VOCs) or environmental toxins.
