Abstract

Nanowires from deposition of pyromellitic diimide (PMDI) from the gas phase and their unique excitation-wavelength-dependent photoluminescence were demonstrated. The luminescence peaks of the PMDI nanowires red-shifted as the excitation wavelength increased. The relationship between the luminescence peak and the excitation wavelength is nearly linear in a broad range of excitation.
