Abstract
We have reported the formation of the a-AgI nanocrystals in the xAgI-(1 - x)(0.5Ag2O-0.5SeO2) glass nanocomposite and β-AgI nanowires along with α-AgI nanocrystals in the heat-treated compositions. We have used X-ray diffraction and transmission electron microscopic studies to detect these nanophases. It is observed that κ-AgI nanocrystals and β-AgI nanowires control the glass transition and the crystallization temperatures. Fourier transform infrared spectroscopic studies have revealed the presence of the SeO2-3 and SeO2-4 structural units in the as-prepared samples as well as in the heat-treated samples. It is also observed that the position of the different infrared bands is independent of the AgI content in the compositions.
