WebThe latter can be explained by saturation effects. 12 The comparison of the excitation spectra of the mixed-ligand Yb III MC with those of Zn 16 Yb(pyzHA) 16 and Zn 16 Yb(quinoHA) 16 revealed the same trend as shown for the absorption spectra, i. e. a red and a blue shift compared to the former and the latter, respectively. WebLuminescence emission measurements made at 4.2°K on KI crystals containing the ions S2 −, Se2 −, and SeS− revealed characteristic banded emission spectra similar to that of O2 −, though both emission and excitation occur at longer wavelengths. The SeS− emission was always accompanied by S2 − and Se2 − emissions, so the emission spectrum was …
