镍钴掺杂ZnNH4PO4的电子谱。6H2O（鸟粪石锌）晶体在室温和液氮温度下均有记录。在镍掺杂的寄主中，能带以八面体对称的方式分配给Ni(II)，而在钴掺杂的寄主中，能带以八面体对称的方式分配给Co(II)，并伴有自旋轨道相互作用。根据结果和分析，对晶体场（Dq）、电子间斥力（B， C）和自旋轨道相互作用（ξ）参数进行了计算。对于镍离子，B = 930, Dq = 950, C = 3550 cm−1；对于钴离子，B = 870, Dq = 980, C = 3830 cm−1,ξ = 500 cm−1。
Abstract Electronic spectra of nickel and cobalt doped ZnNH4PO4 .6H2O (Zinc struvite) crystals are recorded both at room and liquid nitrogen temperatures. In nickel doped host, bands are assigned to Ni(II) in octahedral symmetry whereas in cobalt doped host they are assigned to Co(II) in octahedral symmetry associated with spin orbit interaction. From the results and analysis, the following crystal field (Dq), interelectronic repulsion (B, C) and spin orbit interaction (ξ) parameters are evaluated. B = 930, Dq = 950 and C = 3550 cm−1 for Nickel ion and B = 870, Dq = 980 and C = 3830 cm−1, ξ = 500 cm−1 for cobalt ion.
