Infrared optical properties of SrBi{sub 2-x}Nd{sub x}Nb{sub 2}O{sub 9} (SBNN) ceramics with different Nd compositions (from 0 to 0.2) have been investigated by near-normal incident reflectance technique. The experimental spectra in the wavenumbers range of 350-1500 cm{sup -1} were analyzed using the...
