Present work reports on the synthesis of Co^sup 2+^, Ni^sup 2+^ and Cu^sup 2+^ ions doped willemite α-Zn^sub 2^SiO^sub 4^ 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 Co^sup 2+^, Ni^sup 2+^ and Cu^sup 2+^ ions in Zn^sub 2^SiO^sub 4^ matrix. The dielectric constant (...'), dielectric loss (..."), and AC conductivity (...) 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.
