A series of MnO-doped zinc soda lime silica glass systems was prepared by a conventional melt and quenching technique. In this study, the x-ray diffraction analysis was applied to confirm the amorphous nature of the glasses. Fourier transform infrared spectroscopy shows the glass network consists of MnO, SiO, and ZnO units as basic structural units. The glass samples under field emission scanning electron microscopy observation demonstrated irregularity in shape and size with glassy phase-like structure. The optical absorption studies revealed that the optical bandgap (E) values decrease with an increase of MnO content. Through the results of various measurements, the doping of MnO in the glass matrix had effects on the performance of the glasses and significantly improved the properties of the glass sample as a potential host for phosphor material.
通过传统的熔融淬火技术制备了一系列MnO掺杂的锌钠钙硅玻璃体系。在本研究中，应用X射线衍射分析来确认玻璃的非晶态性质。傅里叶变换红外光谱表明玻璃网络由MnO、SiO和ZnO单元作为基本结构单元组成。场发射扫描电子显微镜观察下的玻璃样品显示出形状和尺寸不规则，具有玻璃相状结构。光吸收研究表明，光学带隙（E）值随着MnO含量的增加而降低。通过各种测量结果，MnO在玻璃基体中的掺杂对玻璃性能有影响，并显著改善了玻璃样品作为磷光体材料潜在基质的性能。
