文摘
- •
Concentration dependences of d–d transition and EPR parameters are studied for MPSC glasses.
- •
[CuO6]10− clusters suffer tetragonal elongation distortions of 3% due to Jahn–Teller effect.
- •
Five-parameter Fourier type functions suitably reproduce observed concentration dependences.
- •
Concentration dependences are analyzed from overall decreasing Λ and reverse rule at x ≥ 0.7.
