摘要：

The spectroscopic properties of Er3+ doped KY(WO4)(2) and Ho3+ doped KYb(WO4)(2) single crystals are reported and related to their X-ray structures. The experimental data include a survey of electronic absorption and emission features as well as vibrational IR and Raman spectra made in the polarized light. The effect of the random distribution of the monovalent and trivalent cations as well as intermolecular interactions between the tungstate anions are discussed. (C) 1998 Elsevier Science B.V.
