Indium Phosphide Quantum Dots (InP/ZnS QD)

Nanografi presents high-quality Indium Phospide Quantum Dots (InP/ZnS) tailored to suit specific requirements.

What are Indium Phosphide/Zinc Sulfide Quantum Dots?

Indium Phosphide/Zinc Sulfide (InP/ZnS) Quantum Dots are synthesized using colloidal methods that enable precise control of particle size and emission wavelength across the visible spectrum (480–700 nm). The ZnS shell passivates the InP core, reducing surface defects and suppressing non-radiative recombination, which enhances photoluminescence efficiency and stability. Surface ligands such as MPA and PEG-COOH allow solubility in aqueous systems, while oleic acid, oleylamine, and thiol groups provide compatibility with organic solvents.

Synthesis and Applications of InP/ZnS Quantum Dots

Indium Phosphide/Zinc Sulfide (InP/ZnS) Quantum Dots are synthesized using colloidal methods that allow precise control of particle size and emission wavelength. The ZnS shell provides stability and improved quantum yield, while surface ligands (such as MPA, PEG-COOH for aqueous systems, and oleic acid, oleylamine, thiol groups for organic systems) enable solubility in both water and oil phases. InP/ZnS QDs are widely applied in bioimaging, biosensing & diagnostics, drug delivery & tracking, environmental monitoring, energy & photocatalysis, and optoelectronics & LEDs. Their cadmium-free composition makes them a safer alternative for biomedical and consumer applications.
