Electronic absorption spectra of Yb(II) ions were recorded in the melts based on NaCl–KCl equimolar mixture (1023 K) and 6NaCl–5KCl–9CsCl (823–1023 K), 3LiCl–2KCl (723–1023 K) и 7LiCl–2KCl–3CsCl (623–1023 K) eutectic mixtures. High intensity absorption peaks due to 4 f 14 → 4 f  135d1 electron transitions were observed. Maxima of the absorption bands are located around 360–380 nm. Extinction coefficients of Yb(II) ions were calculated and the effect of temperature, concentration and melt cationic composition on the positions and intensity of the absorption bands in the spectra of Yb(II) ions was analyzed.
