Product Introduction:
Quantum dot (QD) powder is a high-performance material designed for advanced display and optoelectronic applications. This product features a CdSe/ZnCdSeS/ZnS core–shell nanostructure with oleic acid surface ligands, ensuring excellent compatibility with host matrices. The engineered structure enhances photoluminescence efficiency while maintaining a narrow emission bandwidth, providing precise color rendering for diffusion plates used in next-generation displays.
This QD powder delivers high luminescence efficiency, a narrow full width at half maximum (FWHM), and remarkable stability under a wide range of processing and operating conditions. The low cadmium content ensures compliance with stringent environmental and safety regulations while preserving the superior optical properties of the material. Furthermore, the surface of the QDs is functionalized with oleic acid ligands, which significantly enhance particle dispersion and prevent aggregation, enabling seamless incorporation into diverse polymer matrices and thin-film formulations. This structural and chemical optimization translates to uniform, reliable, and high-quality emission in final optoelectronic devices.
Our product is primarily used in quantum dot diffusion plates, which are essential components in modern display technologies and play a critical role in enhancing color accuracy, brightness, and overall visual performance. By converting and optimizing the light emitted from backlight sources, these diffusion plates help achieve a wider color gamut and more vivid image quality in display panels. Our QD powder boasts excellent performance, which can ensure uniform light distribution on the panel, reduce color variations, and enhance the reliability of the display. It is suitable not only for liquid crystal display (LCD) backlights but also for advanced devices such as micro light-emitting diode (micro-LED) and quantum dot light-emitting diode (QLED) displays, as well as high-performance lighting systems. Furthermore, its low cadmium content and robust stability support safer, long-lasting operation, making it a reliable choice for both consumer electronics and professional applications.
The QD powder can be incorporated into host polymer matrices through melting, blending, or dispersing to form uniform quantum dot layers. For example, it can be mixed with polymers such as PMMA or PS, processed into masterbatch particles, or directly blended with the polymers, and then formed into single- or multi-layer diffusion plates. These methods ensure even distribution of quantum dots, high luminescence efficiency, and precise color performance, which also allows flexibility for various fabrication processes and device designs.
