可持续的锰基荧光材料Sustainable Manganese-Based Phosphors
➀ 杜塞尔多夫大学和因斯布鲁克大学合作研究,提出使用锰基荧光材料替代LED中稀土元素(如铕、铈)的可持续方案;
➁ 实验表明,锰离子(Mn2+)在碱金属硅酸盐结构中可实现高温下稳定的白光发射,或替代现有双稀土荧光层设计;
➂ 该技术旨在解决稀土开采的地缘政治风险和成本问题,同时提升材料可得性与LED在150°C高温工作环境下的热稳定性。
➀ A joint research project by Heinrich-Heine-Universität Düsseldorf and Universität Innsbruck explores manganese as a sustainable alternative to rare-earth elements in LED phosphors;
➁ Mn2+ in alkali lithosilicates demonstrates stable white-light emission under high temperatures, potentially replacing dual rare-earth phosphors in LEDs;
➂ The innovation addresses geopolitical and cost challenges of rare-earth mining while improving material accessibility and thermal performance for lighting applications.
