Abstract
The EPR spectra of Cu2+ in l-histidinium dihydrogen phosphate phosphoric acid at room temperature reveal the presence of two magnetically inequivalent Cu2+ sites in the lattice. The principal values of the g- and A-tensors indicate existence of rhombic symmetry around the Cu2+ ion. From the direction cosines of the principal values of the g- and A-tensors, the locations of Cu2+ in the lattice have been identified as substitutional sites. Optical absorption study shows four bands confirm the rhombic symmetry. Photoluminescence study also confirms the rhombic symmetry around the ions.
