Abnormal behavior of optical signal transfer in π-conjugated organic microplates and focused electron-beam-treated nanorods

•Observation of abnormal behavior in Raman and photoluminescence (PL) signal transfer in organic CN-TSDB microplates.•Observation of abnormal behavior in PL signal transfer in focused electron-beam-treated rubrene nanorods.•Abnormal behavior represents that output optical signals decreased exponentially, but increased drastically from the center of sample or the point of electron-beam treatment.
