Abstract

Rare-earth-free Sr(Ca)₂Ga₂GeO₇ phosphors exhibiting self-activated luminescence properties were synthesized by solid-state method. The incorporation of Ca in place of Sr resulted in a pronounced redshift in the emission spectrum, enabling a closer alignment with the absorption spectrum of chlorophyll. This advancement offers increased flexibility in designing blue LEDs optimized for diverse crop growth applications.

不含稀土的 Sr(Ca)2Ga2GeO7 荧光粉，具有钙替代诱导的红移发射，与叶绿素的吸收完全一致

通过固态方法合成了具有自激活发光特性的无稀土 Sr(Ca)2Ga2GeO7 荧光粉。用 Ca 取代 Sr 后，发射光谱发生了明显的红移，从而更接近叶绿素的吸收光谱。这一进步提高了设计蓝光 LED 的灵活性，优化了其在各种作物生长应用中的性能。
