Studies on structural by applying X–ray diffraction (XRD) characterization found that all compounds formed in monoclinic, P2 1 /n symmetry with reduction of lattice parameters and unit cell volume as dopant concentration increased. The formation of Te 6+ /Mn 6+ –O–Li + octahedral structure can be confirmed with the presence of peaks at certain wavenumbers indicating vibrations of Te – O or Mn – O bonds. As dopant concentration increased, field emission scanning electron microscope (FESEM) characterization found that the increasing trend of formation in grains sizes from x = 0.02 to x = 0.08, and its effects towards dielectric properties which were conducted by electrochemical impedance spectroscopy (EIS) studies were discussed in this paper. Other discussions included were regarding the significant effect of dopant towards optical band gap, E opt and absorption frequencies of prepared compounds compared to pristine compound indicating its promising potential for optoelectronic device application.
