Abstract

The anisotropic properties of a nonlinear optical (NLO) material are of critical importance for comprehending the intrinsic characteristics and evaluating the further applications. However, due to the severe layered growth habits, the anisotropic investigations of the NLO crystal CdTeMoO6 with a quasi-two dimensional structure have been severely hindered. Here, a detailed study of the bulk growth, exhaustive thermal properties and polarized Raman spectra for CdTeMoO6 single crystal are provided and all of them exhibit obvious anisotropic characteristics. Based on high quality crystal CdTeMoO6, the spontaneous Raman spectra along X and Z-axis with different configurations show the strongest Raman shifts at 921.6 and 944.1 cm-1. More importantly, the relationship between structure and the anisotropic physical properties, including thermal expansion, specific heat, thermal diffusion, thermal conductivity and hardness of the CdTeMoO6 crystal have also been systemically discussed, which provide a guidance for the further application of CdTeMoO6.
