Abstract

In this study, the authors attempted to propose the very first study on fabrication and characterization of zinc-boro-silicate (ZBS) glass-ceramics derived from the ternary zinc-boro-silicate (ZnO)(BO)(RHA) glass system through a conventional melt-quenching method by incorporating rice husk ash (RHA) as the silica (SiO) source, followed by a sintering process. Optimization of sintering condition has densified the sintered samples while embedded beta willemite (β-ZnSiO) and alpha willemite (-ZnSiO) were proven in X-ray diffraction (XRD) analysis. Field emission scanning electron microscopy (FESEM) has shown the distribution of willemite crystals in rhombohedral shape crystals and successfully form closely-packed grains due to intense crystallization. The photoluminescence (PL) spectra of all sintered ZBS glasses presented various emission peaks at 425, 463, 487, 531, and 643 nm corresponded to violet, blue, green, and red emission, respectively. The correlation between the densification, phase transformation, microstructure, and photoluminescence of ZnSiO glass-ceramic phosphor is discussed in detail.

摘要

在本研究中，作者尝试开展了第一项关于通过传统熔体淬火法制备和表征源自三元锌硼硅酸盐（ZnO）（BO）（RHA）玻璃体系的锌硼硅酸盐（ZBS）微晶玻璃的研究，该方法通过掺入稻壳灰（RHA）作为二氧化硅（SiO）源，随后进行烧结过程。烧结条件的优化使烧结样品致密化，同时在X射线衍射（XRD）分析中证实了嵌入的β-硅锌矿（β-ZnSiO）和α-硅锌矿（-ZnSiO）。场发射扫描电子显微镜（FESEM）显示了硅锌矿晶体以菱形晶体形式分布，并且由于强烈的结晶作用成功形成了紧密堆积的晶粒。所有烧结ZBS玻璃的光致发光（PL）光谱在425、463、487、531和643 nm处呈现出各种发射峰，分别对应于紫色、蓝色、绿色和红色发射。详细讨论了ZnSiO微晶玻璃荧光粉的致密化、相变、微观结构和光致发光之间的相关性。
