摘要：
We report on the conversion of non-luminescent conventional poly(methylmethacrylate) (PMMA)based electron-beam resists into luminescent materials when used as negative-tone resists, that is, when exposed to high electron irradiation doses. Raman spectroscopy reveals the chemical transformation induced by electron irradiation which is responsible for the observed luminescence in the visible (blue) region. The emission intensity from exposed PMMA-based patterns can be controlled by the electron irradiation dose employed to create them. (C) 2012 Elsevier B.V. All rights reserved.
