Investigation the visibility of fabrication of an Electro-optic sensor Using LiNbO3 crystal implanted Mn ions

The effect of the ion implantation of Fe, Mn on LiNbO3, as well as the dispersion of Ag colloids in LiNbO3 were studied using electron paramagnetic resonance (EPR). EPR measurements on these crystals were performed as a function of fluence at room temperature. The fluence was 1x10(14) and 1x10(16) ions/cm(2) for Fe and 2x10(16) ions/cm(2) for Ag. The unpaired carrier concentration increases with increasing fluence. The photosensitivity of these crystals was determined by observing in situ the effect of the laser illumination on the EPR signal and measuring the decay and the growth of the EPR signal. EPR and optical absorption showed significant differences in the dispersion of the colloids with implant temperature and implant order.
