Abstract Ln0.8Lu0.2TiNbO6 (Ln = Ce, Pr, Nd & Sm) are synthesized through conventional solid state ceramic route. The XRD, FT Raman and FT IR studies revealed that the samples have aeschynite orthorhombic symmetry. The samples are sintered at 1230 ∘C. Using SEM technique, microstructure of the sintered samples is analyzed. The dielectric properties of all the samples in the radio as well as microwave frequencies are studied. UV spectra of the samples are recorded and the optical band gap is estimated from the Tauc's plots. The samples are found to be photoluminescent materials with emissions at violet and green regions.
