Microstructure properties of lead silicate glasses

Abstract

In the present work, lead silicate glasses have been prepared withdifferent amount of lead oxide content. Structure properties such asX-ray diffraction, AFM, and FTIR analyses have been done. Theexceeding of PbO content more than 25wt% revealed a decreasing indensity. The X- ray revealed that the strongest peak related toHexagonal silica dioxide and the other crystal phases formed wererelated to silica oxide (SiO2) and lead oxide (PbO). Growth anddecayed phases in X-ray have been observed with changing leadoxide content. Homogeneous surface was obtained using AFManalyzer with an average diameter around 100 nm. Infrared spectrumis characterized by the presence of large absorption band between1200 and 900cm-1 and have its maximum at 1080 cm-1 which istypical to stretching vibrations of Si–O–Si bonds, another bandsnoticed were attributed to Pb–O–Pb, Pb–O–Si, [AlO4]-tetrahedron,and to Si–O–Al bond.

Effect of Annealing Times on the Structural and Optical Properties of PbO Thin Films Prepared by D.C Sputtering

“…A strong peak at 1393 cm -1 corresponds to the Pb-O stretching, and another peak at 682.9 cm -1 indicates the presence of lead [25]. The transmission peak at 460 cm -1 indicates the presence of (Pb-O) stretching vibration mode [26,27]. The peak around 833 cm -1 is due to the Pb-O vibrations, and the peak around 700 cm -1 is related to the asymmetric bending vibration of Pb-O-Pb [28] [29].…”
