Ytterbium-doped InP emits a characteristic luminescence band near 1.0 \ensuremath{\mu}m, arising from intra-4f-shell transitions of ${\mathrm{Yb}}^{3+}$ (4 ${\mathrm{f}}^{13}$ ). A Zeeman analysis of the complex set of emission lines, in magnetic fields up to 22 T, reveals that the spectrum arises almost entirely from only one type of cubic Yb center, presumably on a substitutional cation site.Ytterbium-doped InP emits a characteristic luminescence band near 1.0 \ensuremath{\mu}m, arising from intra-4f-shell transitions of ${\mathrm{Yb}}^{3+}$(4${\mathrm{f}}^{13}$).

Photoluminescence excitation spectroscopy on InP: Yb

J. Wagner, J. C. Windscheif, Helmut Ennen

Photoluminescence excitation measurements were performed on InP: Yb, using a tunable LiF: ${\mathrm{F}}_{2}^{+}$ colorcenter laser. The excitation spectra show that only one dominant ${\mathrm{Yb}}^{3+}$ ( $4{f}^{13}$ ) center is responsible for the complex set of emission lines observed in the 1.0-\ensuremath{\mu}m spectral range. With the combination of the present results with data obtained by photoluminescence experiments the observed emission lines can be ordered into a level scheme with a twofold-split initial ( $^{2}F_{\frac{5}{2}}$ ) and a threefold-split ( $^{2}F_{\frac{7}{2}}$ ) ground state.Photoluminescence excitation measurements were performed on InP: Yb, using a tunable LiF: ${\mathrm{F}}_{2}^{+}$ colorcenter laser.
