We observed ultraviolet and visible up-conversion signals with maximum intensity at 383 nm; 407; nm; 457; 474; 525; 552; 652; 696; 772; 801; 814 nm and 848 nm from the 4f states of erbium-doped KYb(WO4)2 single crystals after pumping at 981 nm (10 194 cm-1) at room temperature (RT) and low temperature (10 K). These emissions were generated after simultaneous excitation of erbium and ytterbium at 981 nm (Yb3+ acts as a sensitizer of Er3+). We discuss the up-conversion mechanism in which three and two photons were involved in the generation of the ultraviolet and visible emissions. © 2006 Elsevier B.V. All rights reserved;
