Abstract

Fine lines of α-Fe₂O₃ have been formed on quartz substrates by laser beam direct writing on metalorganic 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 to 50 m in diameter. A series of characterizations have been conducted on the written lines by employing different techniques ranging from thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy, scanning electron spectroscopy (SEM), and x-ray diffraction (XRD) to transmission electron microscopy (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 also been studied.
