| Popis: | ErO6 complexes, where every Er3+ ion is surrounded by six oxygen atoms forming an octahedron with C3v point symmetry are found to explain the strong Stark splitting of the characteristic Er3+ emission observed in the 1460–1610 nm range. An a-Si:H matrix serves as an ideal semiconductor host to permit co-doped O atoms to form an optimal ligand field around Er3+ ions. |
