Emerging technologies are demanding innovative properties of glasses. In this work Cerium Oxide is used as dopant in Zinc-Tellurite samples and its effects on the properties of the glass are investigated. Thermal analysis and X-ray diffraction confirmed the amorphous nature of all samples. The bivalent nature of Cerium is investigated spectroscopically and an strong redshift induced by the dopant is attributed to charge transfers O${}^{2-}\to$Ce${}^{4+},$ while the 4f-5d transition of Ce${}^{3+}$ could not be identified in absorption or luminescence measurements. Yellow/red (570/650 nm) emission under 410/450 nm pumping were observed and are originated from Te${}^{4+}$ ions, which absorbs light in the UV/blue region of the spectrum. The incorporation of some Cerium Oxide enhanced the visible luminescence, though we found no evidence that Cerium ions play some role in the radiative process. The luminescence is enhanced though due changes in the glass network induced by the dopant.

新兴技术要求眼镜的创新性能。在这项工作中，氧化铈被用作锌白铁矿样品中的掺杂剂，并研究了其对玻璃性能的影响。热分析和X射线衍射证实了所有样品的无定形性质。光谱研究了铈的二价性质，掺杂剂诱导的强红移归因于电荷转移O${}^{2-}\to$策${}^{4+}，$ 而Ce的4f-5d过渡${}^{3+}$在吸收或发光测量中无法识别。在410/450 nm泵浦下观察到黄色/红色（570/650 nm）发射，其起源于Te${}^{4+}$离子，吸收光谱的紫外线/蓝色区域中的光。尽管我们没有发现铈离子在辐射过程中起一定作用的证据，但掺入一些氧化铈会增强可见光的发光。尽管由于掺杂剂引起的玻璃网络的变化，但是发光增强。
