摘要：

Organic light emitting material direct writing is demonstrated based on nanomaterial enabled laser transfer. 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 low laser energy (0.05 J/cm(2)) while maintaining good fluorescence. The technique may be well suited for the mass production of temperature sensitive organic light emitting devices. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.3001803]
