A catalyst layer of Fe(NO₃)₃ was patterned on a silicon substrate by using a copper grid as a mask. The nanorods were grown via annealing milled boron carbide powders at 1300°C in a flow of nitrogen gas. The as-grown nanorods exhibit uniform morphology and the catalyst pattern precisely defines the position of nanorod deposition. Cathodoluminescence(CL) spectra of the nanorods show two broad emission bands centered at 3.75 and 1.85eV. Panchromatic CL images reveal clear patterned structure.This work is financially supported, in part, by The Australian Research Council under the nanotube program of the Center for Functional Nanomaterials.http://www.sherpa.ac.uk/romeo/issn/0003-6951..."Publishers version/PDF may be used on author's personal website, institutional website or institutional repository" from SHERPA/RoMEO site (as at 6/10/15).
