EPR Analysis of Cu2+ ion Doped Potassium borodicitrate Single Crystal

In our present investigation single crystals of Potassium borodicitrate (KBDC) (for a fixed content- host lattice) with Cu2+, guest species, as dopant (at four 0.2, 0.5, 1 and 2 g) in weight ratio have been synthesized at room temperature by using slow evaporation method. These as-synthesized 4 subjected to Electron Paramagnetic Resonance (EPR) studies. The EPR spectrum shows that 0.5 g KBDC give equidistant hyperfine lines the perfect symmetry confirms localization paramagnetic impurity, within it reveals maximum absorption signals happens Cu2+ than any other concentrations reference 20° horizontal plane normal vertical recording same angular projection. Spin Hamiltonian calculations are used obtain spectroscopic field splitting factor g-tensor values, gxx = 2.0421, gyy 2.1962, gzz 2.2827 A-tensor values Axx 150, Ayy 112 Azz 134. K–O bond length associated directional cosines tensor reveal is located interstitially. This optimized crystal has furtherance Single cystal X-ray diffraction (SXRD), Fourier transform infrared Spectrascopy (FTIR).
