Description
Spectral-kinetic studies have been performed for LiY1-xYbxP4O12 (x = 0; 0.1; 0.9) phosphates at T = 8-320 K using synchrotron radiation for excitation within the 5-17 eV energy range. Mechanisms for the excitation of Yb3+ charge transfer and f-f luminescence are discussed. The quasimolecular character of Yb3+ charge transfer luminescence (CTL) is pointed out. The central Yb2+ ion and hole delocalized over the surrounding ligands are proposed for consideration as a 'charge transfer cluster' (Yb2+ CT cluster). Possible mechanisms of Yb3+ CTL quenching are presumed
