Abstract

Abstract: We have directly fabricated a diffraction grating onto platelike single crystals made of an organic semiconducting oligomer by electron beam lithography followed by reactive-ion etching. The decrease in the grating period resulted in photoexcited spectrally narrowed emission peaks related to the first-order diffraction from the crystal edge without outstanding quenching of the crystal. This work is expected to lead to the realization of organic semiconductor lasers.
