最近，更节能的照明和高性能显示技术的趋势增加了对某些材料的需求，这些材料在潜在的供应限制方面被认为是“关键的”。在本文中，我们评估了这些关键材料的替代可能性，并分析了技术趋势对其短期需求的影响。用更先进的发光二极管（LED）技术取代荧光灯，将显著降低对铕和钇的需求，但对镓和铟的需求将增加。到2020年，照明行业将不再大量使用锗和铽。下一代照明技术-有机LED（OLED）-预计将消除对铟以外的关键材料的需求。然而，OLED技术在普通照明中的广泛采用预计要到2025年才能实现。
Trends towards more energy efficient lighting and high performance display technologies have recently increased the demand for certain materials, which are considered ‘critical’ in terms of potential supply constraints. In this article, we assessed the substitution possibilities of these critical materials and analysed the impact of technological trends on their short‐term demand. Substitution of fluorescent with more advanced light‐emitting diode (LED) technology significantly decrease the demand for europium and yttrium, though, demand for gallium and indium will increase. Germanium and terbium will no longer be significantly used by the lighting sector by 2020. The next‐generation of lighting technology – organic‐LED (OLED) – is expected to eliminate the need for critical materials with the exception of indium. However, a wide adoption of OLED technology in general lighting is not expected before 2025.
