Sahoo, S. Thakur, R.B. Tokas, N.M. Kamble] Refractive-index tailoring and morphological evolutions in two different thin film composite systems of gadolinia-silica (Gd2O3:SiO2) and zirconia-silica (ZrO2:SiO2) deposited through reactive electron-beam codeposition processes are discussed in this research paper. For Gd2O3:SiO2 the refractive-index tuning has been achieved from 1.45 to 2.18, whereas in the case of ZrO2:SiO2 the achieved tunable range is from 1.45 to 2.45 in the ultraviolet region. Under certain compositional mixings with lower silica fractions both the systems demonstrated relative microstructural and morphological densifications. Such evolutions were very successfully derived through phase-modulated ellipsometry and atomic force microscopy. The composition-dependent refractive-index tailoring and microstructural densifications have been investigated by adopting Tauc-Lorentz and single-effective-oscillator models. The morphological correlation functions have also very aptly supported such evolutions in these composite films. These experimental results indicate their favourable properties and applicability down to the extreme ultraviolet wavelength region of the electromagnetic spectrum. Springer-Verlag, 2007 Sahoo N.K.
