Nanomaterial Enabled Laser Transfer of Temperature Sensitive Organic Light Emitting Diode Materials

Organic material direct writing is demonstrated based on nanomaterial enabled laser transfer (NELT). Through utilization of 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 laser induced forward transfer at irradiation energies and temperatures lower than commonly used. The technique may be well suited for the mass production of temperature sensitive devices.
