Paper Abstract

Fine lines of (alpha) -Fe2O3 have been formed on quartz substrates by laser beam direct writing on metalorganic (MO) spin-coated films. A modulated krypton ion writing laser beam and a He-Ne probing laser beam were colinearly focused onto the films with a spot size about 10 - 50 micrometers . A series of characterizations were conducted on the written lines by employing characterization techniques ranging from TGA, FTIR, SEM, XRD, to TEM. In this way a better understanding has been achieved regarding the metalorganic decomposition mechanism, structure and morphology of the laser written lines. From the time-resolved transmittance change induced by the krypton ion laser pulse irradiation, transient behavior of laser decomposition process of metalorganic materials has been studied.
