Organic material direct writing was demonstrated based on nanomaterial enabled laser transfer (NELT). Through proper nanoparticle size and type, and the laser wavelength choice, a single laser pulse could transfer well defined and arbitrarily shaped tris-(8-hydroxyquinoline)Al patterns ranging from several microns to millimeter size. The unique properties of nanomaterials allow the laser induced forward transfer process to be effected at irradiation energies and temperatures lower than commonly used. The technique may be well suited for the mass production of temperature sensitive devices.
