Abstract
The possibilities of Yb3+ doped Y3Al5O12, LiNbO3 and NaBi(WO4)2 crystals as materials for optical temperature sensor (OTS) based on fluorescence intensity ratio (FIR), absorption coefficient ratio (ACR) and relative zero-phonon line intensity (ZPLI) techniques are discussed. The operating temperature regions and average sensitivity for the considered OTSs are determined. It is shown, that the ZPLI technique is more effective for OTS at cryogenic temperatures, whereas FIR and ACR one – at high (above room) temperature range.
