摘要

Novel crystals of strontium incorporated nickel cadmium oxalate (SNCO) trihydrate were grown by single diffusion method in silica hydro gel by optimizing various growth parameters. Field emission scanning electron microscopic (FESEM) images show the morphology of the crystal surface and the existence of Sr, Ni, Cd, C and O elements in the crystal lattice were identified using energy dispersive X-ray (EDX) analysis. The occurrences of C–O, C=O, C–C, O–H and M–O bonds were observed using Fourier transform infrared (FTIR) spectrophotometer. Powder X-ray diffractogram reveals the high crystallinity of the SNCO crystals, and exhibit triclinic crystal system with P-1 space group. Thermal studies (TG/DTG/DTA/DSC) show the high thermal stability (TS > 600º C) of grown crystals. The high energy gap (Eg = 5.420 eV) from the UV–Visible absorption spectroscopy confirms the insulating behaviour of the crystals. Low electrical conductivity (μA), high leakage resistance (MΩ) and the variation of dielectric constant, dielectric loss, AC conductivity with frequency were studied and reported.
