Abstract
Possibilities of the use the Yb3+ doped crystals (Y3Al5O12, NaBi(WO4)2,LiNbO3) as materials for optical temperature sensor based on temperature dependences of zero-phonon spectral lines are discussed. Temperature dependences of intensities of zero-phonon transitions between individual Stark states of Yb3+ ion due to Debye - Waller factors, homogeneous widths and shifts of the spectral lines in a range from 960 to 1060 nm are investigated. The operation temperature regions and average sensitivities for optical temperature sensors under consideration are determined.
