Optical spectra and thermal properties of double perovskite Ba2LuTaO6 material.

Results of optical spectra and thermal properties of double perovskite Ba 2 LuTaO 6 compound material are reported using the full-potential linearized augmented plane wave method and the quasi-harmonic Debye model. Optical properties reveal that the transparent nature of the material under focus covers a broad range of solar spectrum including the infrared, visible and lower part of the ultraviolet ranges. The influence of temperature and pressure effects on volume unit cell, bulk modulus and heat capacity is examined and discussed. [ABSTRACT FROM AUTHOR]
