Abstract
- In this paper, the crystallization behavior of 50ZnO:47B<subscript>2</subscript>O<subscript>3</subscript>:3Nb<subscript>2</subscript>O<subscript>3</subscript>:0.5Eu<subscript>2</subscript>O<subscript>3</subscript> (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<subscript>3</subscript>B<subscript>2</subscript>O<subscript>6</subscript>, β-Zn<subscript>3</subscript>B<subscript>2</subscript>O<subscript>6</subscript> and ZnNb<subscript>2</subscript>O<subscript>6</subscript>). By calculating crystal parameters, it was found that europium ions are successfully incorporated in the β-Zn<subscript>3</subscript>B<subscript>2</subscript>O<subscript>6</subscript>. Photo-luminescent spectra showed increased emission in the resulting glass-ceramic samples compared to the parent glass sample due to higher asymmetry of Eu<superscript>3+</superscript> 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. [ABSTRACT FROM AUTHOR]
