Borate glasses (BG) doped with different amounts of ZnO (0-0.6 mol%) were formed by the traditional melt quenching technique. The different glasses so made were characterized using different characterization techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), and UV-Vis absorption optical properties. The XRD patterns showed an amorphous structure with one broad peak at 2θ = 29°, while the phonons bands were studied in terms of the FTIR bands. Optical properties of the glasses were studied using UV-Vis absorption spectra in the range 190-1100 nm, in which the prominent band lies at about 261.5 nm of peak position, from which the bandgab (E) was calculated from its edge using Tauc's plot, with E ~ 3.5 eV. The laser irradiation showed no significant changes in the absorption bands, despite a significant change observed in the amorphous behavior in the XRD pattern. The cell viability was performed for two samples of the BG and 0.6 mol% ZnO doped using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay method. The result showed better cell viability and low toxicity. So, ZnO doped BG can be used in various biomedical applications.
掺有不同量 ZnO（0-0.6mol%）的硼酸酯玻璃（BG）通过传统的熔融淬火技术形成。使用不同的特征技术对不同的玻璃进行了表征，例如 X 射线衍射（XRD）、傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）和紫外-可见吸收光学性质。XRD 图谱显示出具有 2θ=29°处一个宽峰的非晶结构，而声子带则根据 FTIR 带进行了研究。使用 190-1100nm 范围内的紫外-可见吸收光谱研究了玻璃的光学性质，其中突出的带位于约 261.5nm 的峰位置，从该位置使用 Tauc 图计算出带隙（E），E≈3.5eV。尽管在 XRD 图谱中观察到非晶态行为发生了显著变化，但激光辐照没有引起吸收带的显著变化。使用 3-（4,5-二甲基-2-噻唑基）-2,5-二苯基-2H-四唑溴盐（MTT）测定法对 BG 和 0.6mol% ZnO 掺杂的两个 BG 样品进行了细胞活力测试。结果表明细胞活力更好，毒性低。因此，ZnO 掺杂 BG 可用于各种生物医学应用。
