Cadmium Selenide Quantum Dots (CdSe/ZnS QD) 625 nm

Cadmium Selenide/Zinc Sulfide (CdSe/ZnS) Core-Shell Quantum Dots, meticulously engineered for a 625 nm peak emission, deliver industry-leading photoluminescent and electroluminescent performance. These nanocrystals feature a high-purity CdSe core protected by an epitaxial ZnS inorganic shell, a structure that effectively passivates surface defects to ensure a high quantum yield and exceptional resistance to photobleaching. Characterized by a remarkably narrow Full Width at Half Maximum (FWHM), these 625 nm dots provide a vibrant, saturated red light that is essential for high-fidelity color rendering. Their robust chemical stability and high extinction coefficients make them a versatile platform for advanced research, allowing for seamless integration into thin-film optoelectronic stacks or functionalization for targeted biological interactions.
