Abstract
We have studied the effect of gamma irradiation to various doses on optical characteristics (optical transmission spectra) of nominally undoped, rare earth-doped, and alkaline earth-doped lithium niobate crystals: LiNbO3, LiNbO3:Y (0.46 wt %), LiNbO3:Y,Mg (0.32, 0.24 wt %), LiNbO3:Mg (0.27 wt %), and LiNbO3:Gd (0.004, 0.04, 0.26, 0.43 wt %). We have examined the influence of the ionizing radiation dose, the nature of dopants, and their concentration on the optical transmission of the gamma-irradiated doped lithium niobate crystals. The results suggest that gamma-induced changes in the optical transmission of LiNbO3:Gd (≃0.004 and 0.04 wt %) crystals can be used for gamma dosimetry in the dose range ≃101 to 1.5 × 104 rad.
