Description

Cadmium Zinc Sulphide is an inorganic compound belonging to the class of II-VI semiconductor materials. This material is significant for its unique optoelectronic properties, which are tunable based on its composition. It is primarily required by manufacturers and research institutions in the semiconductor, photonics, and specialty pigment industries for advanced applications.

Application

• Semiconductor and Optoelectronic Devices: Used in the fabrication of light-emitting diodes (LEDs), photodetectors, and thin-film transistors due to its tunable bandgap.
• Phosphors and Luminescent Materials: Serves as a base material for afterglow pigments, electroluminescent displays, and X-ray scintillators.
• Specialty Pigments and Coatings: Employed in formulations requiring specific optical properties, such as IR-reflective or conductive coatings.
• Photocatalytic Research: Investigated as a potential catalyst for water splitting and pollutant degradation under visible light.
• Quantum Dot Synthesis: Acts as a precursor for developing cadmium zinc sulfide (CdZnS) quantum dots with precise size and emission control.
• Solar Cell Technology: Explored as a buffer or window layer in thin-film photovoltaic cells like CIGS (Copper Indium Gallium Selenide).
• Security Printing: Utilized in anti-counterfeiting inks and tags that exhibit specific luminescent signatures.
