melt‐quenching method and the effect of addition of 0–15 wt% of α‐alumina (Al2O3) on the
spectroscopic, dielectric, and optical properties of ZBS has been studied. Structural and
microstructural modifications of ZBS with alumina addition were studied using X‐ray
diffraction, spectroscopic (Raman and IR) and scanning electron microscopic techniques.
The effect of Al2O3 on the photoluminescence properties of ZBS was also investigated.
