Cadmium Selenide Quantum Dots (CdSe/ZnS QD) 525 nm

Cadmium Selenide/Zinc Sulfide (CdSe/ZnS) Core-Shell Quantum Dots, precision-tuned to a 525 nm emerald-green emission, represent the benchmark for high-performance monochromatic light sources at the nanoscale. These nanocrystals feature a meticulously engineered CdSe core encapsulated by an epitaxial ZnS shell, which serves as a potent inorganic barrier to suppress surface defects and non-radiative recombination. This architecture results in near-unity photoluminescence quantum yields and exceptional chemical stability. Characterized by an ultra-narrow FWHM (Full Width at Half Maximum) and high extinction coefficients, these 525 nm dots deliver unparalleled color purity and brightness. Their robust photostability and predictable surface chemistry make them an ideal platform for high-end optoelectronic integration and advanced fluorescence-based diagnostic assays.
