    Abstract: We report on a detailed spectroscopic study of Eu3+ ions in the monoclinic KYb(WO4)2 crystal. The polarized room and low-temperature absorption spectra are measured. The maximum ¿abs corresponding to the 7F1 ¿ 5D1 transition is 1.32×10¿20 cm2 at 534.2 nm with a bandwidth of 0.7 nm (for E||Nm). The Stark sub-levels of the excited mulitplets are determined. A Judd-Ofelt analysis is applied to the Eu3+:KYb(WO4)2 crystal to determine the probability of spontaneous transitions, radiative lifetimes and luminescence branching ratios. Within the strong configuration interaction (SCI) approximation, the intensity parameters are ¿2=4.757, ¿4=2.295, ¿6=1.644 [10¿20 cm2] and ¿f=50160 cm¿1. The radiative lifetime of the 5D0 state is 351 µs. The maximum stimulated-emission cross-section corresponding to the 7F1 ¿ 5D1 transition is 1.44×10¿20 cm2 at 703.2 nm (for E||Nm). Under UV excitation, the Eu3+:KYb(WO4)2 crystal provides intense red photoluminescence with CIE coordinates, x=0.675, y=0.325.
