Lanthanum hexaboride nanoparticles, with high emission electrons in cathode materials and peculiar blocking near infrared wavelengths, were applied for many aspects.
Lanthanum hexaboride (La B 6, also called lanthanum boride and LaB) is an inorganic chemical, a boride of lanthanum. It is a refractory ceramic material that has a melting point of 2210 °C, and is insoluble in water and hydrochloric acid. It has a low work function and one of the highest electron emissivities known, and is stable in vacuum.
There seems to be some miscommunication here. Quasiparticles are not free electrons (if I understand the Reviewer's comment correctly), however, we agree that the title could be more descriptive, and have changed the title to "Tuning the Surface Plasmon Resonance of Lanthanum Hexaboride to Absorb Solar Heat: A Review" 2.
