The stark energy level split of (2F7/2, 2F5/2) of ytterbium ion in glasses are derived from room temperature absorption and emission spectra. It is shown that the stark energy split increases as the base varies from phosphate to tellurite glasses, and the first and second stark energy levels lay in range of 150 - 250 cm-1, 350 - 450 cm-1 over ground, the first over ground has smaller energy and thus larger Boltzmann heat effect and is difficult in lasing at this terminal level. The second level is 350 cm-1 over ground and can be considered as the terminal level whose lasing wavelength varies from 1000 nm to 1020 nm. The partition function ratio of the upper and lower levels of ytterbium ion is calculated and more accurate reciprocity equation by which emission cross section is determined from absorption spectra is obtained from stark energy levels.
