Pulsed laser deposition of organic thin ®lms
نویسندگان
چکیده
Excimer laser pulsed deposition was applied to the deposition of organic thin ®lms on sapphire and on glass. The thin ®lms were analyzed by X-ray diffraction (XRD), micro-Raman spectroscopy and ESCA. It was found that the properties of the ®lms were very close to that of the target materials. Strong photoluminescence was observed for both Alq3 and N,N 0-diphenyl-N,N 0-bis(3-methylphenyl)-(1,1 0-biphenyl)-4,4 0diamine (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 Alq3/GaP multi-layers was observed. q 2000 Elsevier Science S.A. All rights reserved.

We report an experimental study on optical and magneto-optical properties of Cesubstituted yttrium iron garnet thin films incorporating gold nanoparticles. Au nanoparticles were formed by heating Au thin film on cubic quartz and garnet substrate in vacuum chamber and a Ce:YIG layer was deposited on them by the aid of Pulsed laser deposition method. A large enhancement of the longitudinal Kerr e...

Epitaxial La0:6Sr0:4MnO3 (LSMO) thin films were grown by pulsed laser deposition. Relationships between magnetic properties of LSMO epitaxial thin films and ablation conditions such as ablated spot area and total incident laser energy in a pulsed laser deposition technique were studied. Ablated spot area was controlled by changing the focus lens position and total laser energy. Epitaxial growth...
متن کاملTunable Schottky Barrier in Photovoltaic BiFeO3 Based Ferroelectric Composite Thin Films
We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...
