摘要

The Co_xZn_1鈭?em>xGa₂O₄ spinels (x = 0.25, 0.5, 0.75, 1) were synthesized by a wet chemistry method-the precursor route via tartarate decomposition. The complex precursors have been characterized by IR, UV-Vis, magnetic measurements and luminescence spectroscopy. XRD, SEM, IR, UV-Vis and luminescence spectroscopy were used for the structural and morphological investigation of Co_xZn_1鈭?em>xGa₂O₄ spinels; magnetic susceptibilities of the spinel were also measured. The X-ray diffraction patterns confirmed the formation of gallate spinel phase, Co_xZn_1鈭?em>xGa₂O₄.
