Abstract
Raman spectra were studied for the cubic ytterbium doped zirconia with 10, 20 and 25% of dopant. This part of investigation deals with region of large wave numbers. Two different excitation sources with wavelength 785 and 532 nm are used. For first time Stokes lines that are independent of the excitation wavelength were observed together with conventional luminescence of ytterbium cation.
