“…The relationship between the average of g factor g, cubic CF parameter D q and the covalency factor N for Cu 2þ in xCuO À ð68 À xÞV 2 O 5 À 32TeO 2 with x = 5, 10, 20, 30 mol% absorption band of Cu 2þ occupying the center of axisymmetrical octahedral symmetry is generally located at 755-1000 nm (1320-1000 cm À1 ). [56][57][58][59] In the optical absorption spectrum of glasses, the position of the absorption band will move towards the infrared spectrum with the increase of CuO content, [60][61][62] further confirming that the calculated D q value decreases with the increase of x concentration is reasonable. For Cu 2þ in different crystals, the range of κ is generally within 0.2-0.6.…”

The defect structure, spin Hamiltonian parameters (SHPs: anisotropic g factors g k and g ⊥ and the hyperfine structure constants A k and A ⊥ ), and their compositional dependence of Cu 2þ in xCuO À ð68 À xÞV 2 O 5 À 32TeO 2 (x = 5, 10, 20, 30 mol%) glasses are quantitatively analyzed by using the higher-order perturbation formula of octahedral complex with tetrahedral elongation distortion. Due to the Jahn-Teller effect, the ½CuO 6 10À group is subjected to tetragonal elongation distortion of varying degrees. D q , N, ρ, κ, and H show nonlinear changes with the concentrations of Cu 2þ . When x = 10 mol% CuO, the degree of distortion (ρ ≈ 0:1%) is the smallest; when x = 30 mol% CuO, the degree of distortion (ρ ≈ 15%) is the largest, which indicates that excessive distortion leads to the appearance of Z-axis oxygen vacancies and the coordination number of copper ions from six to four. The increasing tendency of the evaluated N and H reveals decreasing covalency of the whole glass system. Present theoretical studies would be useful to the explore the structural properties and optical applications of glass with different CuO concentrations.
