Lithium fluoride nanowires via vapor-liquid-solid growth

Abstract

Lithium fluoride (LiF) nanowires with diameter of 100nm–500nm and length of tens of microns were synthesized via vapor-liquid-solid growth. Cubic-structured single-crystalline LiF nanowires grew along the ⟨001⟩ and ⟨110⟩ crystallographic directions, respectively. The growth of the LiF nanowires was proposed by the catalysis of Zn droplets decomposed from the ZnO. The LiF nanowire could be a potential candidate for the room-temperature tunable color center nanolaser.
