量子点（QD）被认为是当前和下一代显示器的理想发光体。因此，迫切需要生产具有高效率和更好色纯度的环保量子点。从这个角度来看，讨论了调整波长和光谱宽度的策略，以优化亮度和色彩空间一致性。研究了影响光物理性质的关键参数，例如 InP QD 核的均匀性、ZnSe 壳的厚度和形状、电子/空穴分布、表面悬挂缺陷、氧化相和晶体结构中的堆垛层错。此外，建议进行定量分析以了解配体的性质，以便实际应用多样化。最近，使用具有受控壳结构的 InP 基 QD 的 QD-LED 显示出未来商业化的潜力。为了进一步发展，需要通过控制无机和有机钝化结构来提高稳定性。
Quantum dots (QD) are regarded as ideal light emitters for current and next-generation displays. Hence, there is an urgent need to produce environmentally friendly QDs that show high efficiency and better color purity. From this perspective, a strategy of tuning the wavelength and spectral width is discussed to optimize the brightness and color space agreement. The critical parameters affecting photophysical properties, such as the uniformity of the InP QD core, the thickness and shape of the ZnSe shell, the electron/hole distribution, surface dangling defects, oxidative phase, and the stacking faults in the crystalline structure, are examined. In addition, quantitative analyses are suggested to understand the nature of the ligands so that practical applications can be diversified. Recently, QD-LEDs using InP-based QDs with controlled shell structure showed potential for future commercialization. For further development, improvement in the stability via the control of inorganic and organic passivating structures is required.
