Description
Summary:In this paper, the crystallization behavior of 50ZnO:47B[sub.2]O[sub.3]:3Nb[sub.2]O[sub.3]:0.5Eu[sub.2]O[sub.3] (G-0 h) glass has been investigated in detail by DSC, XRD and TEM analysis. The luminescent properties of the resulting glass-ceramics were also investigated. By XRD and TEM analysis, crystallization of several crystalline phases has been proved (α-Zn[sub.3]B[sub.2]O[sub.6], β-Zn[sub.3]B[sub.2]O[sub.6] and ZnNb[sub.2]O[sub.6]). By calculating crystal parameters, it was found that europium ions are successfully incorporated in the β-Zn[sub.3]B[sub.2]O[sub.6]. Photo-luminescent spectra showed increased emission in the resulting glass-ceramic samples compared to the parent glass sample due to higher asymmetry of Eu[sup.3+] ions in the obtained crystalline phases. It was established that the optimum emission intensity is registered for glass-ceramic samples obtained after 25 h heat treatment of the parent glass.
