For ecologically friendly and energy-efficient solid-state light sources, phosphors with low color-correlated temperatures (CCTs) and high color rendering indices (CRIs) are greatly desired. Herein, a co-precipitation method is used to modulate the fluorescence color of ZnO nano- material for bright multi-color light emitting diodes (LEDs) applications. The structural, thermal, morphological and optical properties of ZnO nanomaterials have been studied. Thermogravimetric analysis (TGA) of the as-synthesized nanomaterials reveals their good thermal stability whereas XPS analysis confirms their chemical states. We demonstrate that after combining ZnO with Ag₂O and MnO₂, the nanocomposite can attain extraordinary luminous tunability as realized by the photoluminescence (PL) properties of the nanomaterials. The estimated Commission Internationale de l’Eclairage (CIE) color coordinates indicate that ZnO, the blue color phosphor can be tuned to orange-red color phosphor (ZnO/Ag₂O and ZnO/MnO${}_2)$ and to white color phosphor (ZnO/Ag₂O/MnO${}_2)$ exhibits fairish color rendering index (CRI) of 84, after composited with Ag₂O and MnO₂. Finally, the ZnO/Ag₂O, ZnO/MnO₂ and ZnO/Ag₂O/MnO₂ nanocomposites have the potential to be utilized as phosphor materials in warm white LED applications because of their extremely pure, robust stability and tunable emission colors. Our findings can be used as a new benchmark for the identification of new phosphors and the tunability of their luminescent color for solid-state lighting applications.

对于生态友好且节能的固态光源，非常需要具有低颜色相关温度（CCT）和高显色指数（CRI）的荧光粉。在此，采用共沉淀方法来调制 ZnO 纳米材料的荧光颜色，以实现明亮的多色发光二极管 (LED) 应用。研究了ZnO纳米材料的结构、热学、形貌和光学性质。合成纳米材料的热重分析 (TGA) 揭示了它们良好的热稳定性，而 XPS 分析则证实了它们的化学状态。我们证明，将 ZnO 与 Ag ₂ O 和 MnO ₂结合后，纳米复合材料可以通过纳米材料的光致发光（PL）特性实现非凡的发光可调性。国际照明委员会 (CIE) 估计的颜色坐标表明，ZnO（蓝色磷光体）可以调整为橙红色磷光体（ZnO/Ag ₂ O 和 ZnO/MnO）${}_2）$和白色荧光粉（ZnO/Ag ₂ O/MnO${}_2）$_{与Ag 2} O和MnO ₂复合后，显色指数(CRI)为84 。最后，ZnO/Ag ₂ O、ZnO/MnO ₂和ZnO/Ag ₂ O/MnO ₂纳米复合材料由于其极其纯净、稳定的稳定性和可调的发射颜色，有可能用作暖白光LED应用中的荧光粉材料。我们的研究结果可以用作识别新型荧光粉及其发光颜色在固态照明应用中的可调性的新基准。
