Abstract

Phosphor development for warm white LEDs (w-WLEDs) is key to enhancing light quality, energy efficiency, stability, and environmental sustainability. Mn-doped phosphors, known for their broad visible emission, are especially promising for UV-pumped w-WLEDs. While halide and garnet systems show potential, they suffer from toxicity and complex synthesis, making ZnO and ZnS attractive, stable alternatives. In this study, tunable full-visible-spectrum ZnS/ZnO:Mn phosphors were synthesized a simple thermal diffusion method. Structural analyses (XRD, Raman) revealed temperature-driven phase evolution, while PL and PLE measurements confirmed strong UV absorption and broad 400-700 nm emission from both host and Mn centers. Emission was effectively tuned by Mn concentration, with the ZnS/ZnO:0.1% Mn sample emitting warm white light (CIE: = 0.35, = 0.37; CCT: 4920 K; decay time: 0.35 ms; activation energy: 0.31 eV). A phosphor-coated LED prototype demonstrated high luminous efficacy (127.7 lm per W), CIE coordinates (, ) = (0.4974, 0.3405), CRI of 72, and a correlated color temperature (CCT) of 2506 K, suitable for warm lighting applications.

摘要

用于暖白色发光二极管（w-WLED）的荧光粉开发对于提高光质量、能源效率、稳定性和环境可持续性至关重要。以其宽可见发射而闻名的锰掺杂荧光粉对于紫外泵浦的w-WLED特别有前景。虽然卤化物和石榴石体系显示出潜力，但它们存在毒性和合成复杂的问题，使得ZnO和ZnS成为有吸引力的、稳定的替代品。在本研究中，通过一种简单的热扩散方法合成了可调谐的全可见光谱ZnS/ZnO:Mn荧光粉。结构分析（XRD、拉曼）揭示了温度驱动的相演变，而PL和PLE测量证实了主体和锰中心都有强烈的紫外吸收和400 - 700 nm的宽发射。发射通过锰浓度有效调节，ZnS/ZnO:0.1% Mn样品发射暖白色光（CIE：x = 0.35，y = 0.37；CCT：4920 K；衰减时间：0.35 ms；激活能：0.31 eV）。一个涂覆有荧光粉的LED原型展示了高发光效率（每瓦127.7 lm）、CIE坐标（x，y）=（0.4974，0.3405）、显色指数为72以及相关色温（CCT）为2506 K，适用于暖照明应用。
