Quantum Dot (QD) Concentrates

Quantum dot (QD) concentrates are highly concentrated dispersions of quantum dots in carefully selected solvents. Compared with traditional QD dispersions, concentrates provide higher loading levels, improved transport stability, and greater formulation flexibility. As a result, they serve as essential intermediate materials for the preparation of functional inks, photoresists, and color conversion layers used in modern display manufacturing. With the rapid advancement of technologies such as quantum dot light-emitting diode (QLED) and micro light-emitting diode (micro-LED) displays, the demand for high-quality QD concentrates continues to grow.

Composition and Structure

Typically, QD concentrates are based on CdSe/ZnCdSeS/ZnS core-shell structures, designed to enhance photoluminescence efficiency and stability. The core-shell architecture protects the quantum dot's active core from oxidation and environmental degradation, while surface modifications improve solubility and compatibility with different matrices. These structural optimizations ensure that QDs maintain consistent emission properties and long-term stability, even under harsh processing conditions.
