High pure cadmium selenide is raw material for electronic emitter, optical conductor, semiconductor, light sensor and other photoelectric device or semiconductors. Low purity CdSe is for pigments normally that is cadmium red.
In optoelectronics, CdSe is highly valued for its use in photodetectors, light-emitting diodes (LEDs), and lasers. Due to its responsiveness to light, CdSe enables high-performance photodetectors, which play a part in cameras, industrial sensors, and scientific equipment that rely on precise light detection. Additionally, CdSe quantum dots widely get applications in LED displays. It offers vibrant colors and energy efficiency, making them essential for high-quality screens and next-generation displays. CdSe-based lasers also find applications in optical communication and data storage technologies.
The photovoltaic industry benefits from CdSe’s capacity to absorb sunlight efficiently, making it useful in thin-film solar cells. CdSe often works as an absorber layer or in conjunction with other materials, like cadmium telluride (CdTe), to improve solar cell efficiency and stability. Its compatibility with CdTE enhances the cell’s power output, making CdSe-based solar technology an attractive solution for renewable energy applications.
In biomedical imaging, CdSe quantum dots offer distinct advantages due to their brightness and stability. These quantum dots can emit in various wavelengths, making them suitable for imaging techniques that require precise, multi-color visualization. In applications like fluorescence microscopy and medical diagnostics, CdSe quantum dots enable high-resolution imaging, supporting advancements in biological research and healthcare diagnostics.
