Carbon-based materials such as graphene oxide are known as attractive candidate to improve the current optoelectronic and laser devices. In this work, neodymium nanoparticles doped zinc-tellurite glass coated with graphene oxide (GO) denoted as ZBTNd (NPs)-GO was prepared via low-cost melt-quenching method and simple spray coating method. The structural properties of the glass system had been carried out by using X-ray diffraction (XRD) and confirmed its amorphous structural arrangement with non-existence of crystalline structure. The TeO3 and BO3 structural units were found dominant in tellurite glass network as determined by Fourier transforms infrared spectrometer (FTIR). High number of oxygen functional groups and stacked of graphene layers on the glass surface were revealed by field scanning electron microscopy (FESEM) and Raman spectroscopy. The optical band gap energy values were found to decrease in the range of 2.665–2.405 eV along with dopant concentration. In the meantime, the refractive index values were found more than n > 2.00 and fall in the range of 2.12 to 2.20. The electronic polarization was calculated by using Lorentz-Lorentz equation and found in the range of 6.516 to 7.211 Å ³. Based on these results, the improvements on optical properties of tellurite glass have been made to be used in laser application.

众所周知，氧化石墨烯等碳基材料是改进当前光电和激光器件的有吸引力的候选材料。在这项工作中，通过低成本的熔体淬火方法和简单的喷涂方法制备了掺杂有氧化石墨烯（GO）的钕纳米粒子掺杂的锌-碲酸盐玻璃，表示为 ZBTNd（NPs）-GO。玻璃体系的结构特性已通过使用 X 射线衍射 (XRD) 进行，并证实了其非晶结构排列，不存在晶体结构。通过傅里叶变换红外光谱仪 (FTIR) 确定，TeO3 和 BO3 结构单元在碲酸盐玻璃网络中占主导地位。场扫描电子显微镜 (FESEM) 和拉曼光谱揭示了玻璃表面上大量的氧官能团和石墨烯层的堆叠。发现光学带隙能量值随着掺杂浓度在 2.665-2.405 eV 范围内降低。同时，发现折射率值大于 n > 2.00 并落在 2.12 至 2.20 的范围内。使用洛伦兹-洛伦兹方程计算电子极化，发现范围为 6.516 至 7.211 ų . 基于这些结果，碲酸盐玻璃光学性能的改进已被用于激光应用。
