Abstract

We show that blue-CL (λ=430nm) can be induced in SrTiO₃ single crystal at room temperature by irradiating it with 60 KeV carbon ion (C^-) beam. An infrared CL-emission (λ=770nm) is induced simultaneously. Transmission electron microscopy (TEM) measurement exhibits an 200 nm thick surface layer formed by the C^- irradiation. We show that the emitting region can be patterned into any desired shape by fabricating the STO surface using Pt-based micro-lithography technique.
