英文摘要	The z-cut LiTaO3 single crystals were irradiated by 6 MeV Xe-ion at the fluences in the range from 1.0 x 10(12) to 1.0 x 10(15) ions/cm(2), or 30, 375, 1980 MeV Kr ions at the fluences in the range from 1.0 x 10(11) to 1.0 x 10(13) ions/cm(2). The irradiated samples were analyzed by optical spectrometer and Rutherford backscattering-channeling spectroscopy. It was found that the UV absorption edge of LiTaO3 shifts toward to longer wavelength (red-shift) as a result of heavy-ion irradiation. In 6 MeV Xe-ion irradiated samples, the red-shifts are weak even at a high fluence of 1.0 x 10(15) ions/cm(2) when the irradiated layer becomes amorphous. However, in 30, 375, 1980 MeV Kr-ion irradiated samples, significant red-shifts were observed even at low fluences. The effects of nuclear energy loss and electronic energy loss on the red-shift of absorption edge in LiTaO3 are discussed. Published by Elsevier B.V.
