Popis:	Present work reports on the synthesis of Co2+, Ni2+ and Cu2+ ions doped willemite α-Zn2SiO4 nanoceramic sol-gel powders. The structural and morphological of these materials were carried out using XRD, Raman and field emission scanning electron microscopy (FESEM), and elemental analysis by EDAX. Both XRD and EDAX results have thus corroborated the doping of Co2+, Ni2+ and Cu2+ ions in Zn2SiO4 matrix. The dielectric constant (ϵ′), dielectric loss (ϵ″), and AC conductivity (σac) properties have been studied as a function of frequency and temperature as well and those results are found to be strongly dependent on dopant ions such trends have successfully been explained based on space charge polarization way following according the standard procedures of Maxwell-Wagner two-layer model.
