Pulsed laser deposition of organic thin films
Excimer laser pulsed deposition was applied to the deposition of organic thin films on sapphire and on glass. The thin films were analyzed by X-ray diffraction (XRD), micro-Raman spectroscopy and ESCA. It was found that the properties of the films were very close to that of the target materials. Strong photoluminescence was observed for both Alq(3) and N,N'-diphenyl-N,N'-bis(3-methylphenyl)-(1, 1'-biphenyl)-4,4'-diamine (TPD), indicating that laser deposition is a viable method for the deposition of these organic materials. An interesting increase in the photoluminescent (PL) signal of Alq(3)/GaP multi-layers was observed.
