In this paper, we report the existence of anisotropic behavior along the crystallographic axes
in optical, electrical and thermal properties of lithium tri borate, a recently developed vacuum
UV-NLO material. The variation of refractive index with the wavelength along the
crystallographic axes was investigated by prism coupling method. The results of impedance
spectroscopy measurement reveal the presence of a strong anisotropy in ionic conductivity
and dielectric constant along the axes and also show the super-ionic conduction behavior …
