Tuning the Surface Plasmon Resonance of Lanthanum

While traditional noble metal (Ag Au and Cu) nanoparticles are well known for their plasmonic properties they typically only absorb in the ultraviolet and visible regions The study of metal hexaborides lanthanum hexaboride (LaB6) in particular expands the available absorbance range of these metals well into the near-infrared As a result LaB6 has become a material of
