Abstract
We show that blue-CL (lambda = 430 nm) can be induced in SrTiO3 single crystal at room temperature by irradiating it with 60 KeV carbon ion (C-) beam. An infrared CL-emission (lambda = 770 nm) 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. (C) 2010 Elsevier B.V. All rights reserved.
