Abstract
Solid-state ceramic lasers have a wide range of applications in industrial, medical, and military applications. This research work presents the fabrication of vacuum sintered Y2O3 ceramics synthesized using co-precipitation method. The impact of sintering additives such as La2O3 and ZrO2 were examined on the structural and morphological traits of Y2O3. The development of pure cubic phases is revealed by X-ray diffraction studies. Williamson-Hall method is used to determine the crystallite size and micro-strain. The incorporation of La3+ and Zr4+ are confirmed through FTIR spectra. The optical characteristics are investigated through UV–VIS spectroscopy. The addition of La3+ and Zr4+ additives increases the densification of Y2O3 ceramic pellets and improves their sintering behavior. The effect of sintering additives on grain size and elemental composition were examined using scanning electron microscopy and energy dispersive spectroscopy.
