Abstract

We have irradiated SrTiO₃ single crystal with 3 MeV-proton (H⁺) beam and found that blue (λ=420nm)-, green λ=500nm)-and infrared (λ=800nm)-frequency photoluminescence (PL) are induced simultaneously at room temperature. TEM and EELS analyses show that an oxygen-deficient amorphous layer is formed at the crystal surface by the proton irradiation. Possible origin of the PL-effect is discussed.
