Abstract

Zinc oxide (ZnO) has been extensively used in areas such as optoelectronics, solar cells, and photocatalysis, among others. Modifying the optical properties of ZnO through different processes can potentially improve the performance of devices based on this material. This work presents the biosynthesis of ZnO by Beaucarnea gracilis leaf extract. The natural extract was mixed with zinc nitrate hexahydrate, Zn(NO3)2·6H2O resulting in a precipitate. Then the precipitate was calcined for 2 h at 400 °C, resulting in a yellowish-ZnO powder. Diffraction laser measurements showed a particle size average of 419 nm. The material exhibited high absorption in the UVA region with photoluminescence at 530 nm. Moreover, from the Tauc plot, a 2.7 eV band gap was obtained. Fourier Transform Infrared (FTIR) spectroscopy results confirmed the ZnO synthesis through 550 cm−1 and 667 cm−1 absorption peaks. To the best of our knowledge, this is the first time that ZnO has been synthesized by the endemic plant Beaucarnea gracilis. A major difference with conventional ZnO is significant reduction in the band gap from 3.3 eV to 2.7 eV. Moreover, the material exhibited photoluminescence at 530 nm by exposure to UV light which is attributed to oxygen vacancies. The increase in the optical absorbance in the UV–Visible region and the reduction in the optical band gap could enhance the performance in solar cells based on ZnO and in photocatalysis processes, allowing the use of visible light sources in addition to UV light.

基于白花蛇舌草的绿色合成获得氧化锌中尺度纳米粒子光致发光
氧化锌(ZnO)已被广泛应用于光电子学、太阳能电池和光催化等领域。通过不同的工艺改变氧化锌的光学特性有可能提高基于这种材料的设备的性能。本研究介绍了用蚕豆叶提取物生物合成氧化锌的过程。天然提取物与六水硝酸锌(Zn(NO3)2-6H2O)混合后产生沉淀。然后将沉淀在 400 °C 下煅烧 2 小时,得到淡黄色的氧化锌粉末。激光衍射测量结果显示其平均粒径为 419 纳米。该材料在 UVA 波段有高吸收,在 530 纳米波段有光致发光。此外,根据陶克曲线图,还得出了 2.7 eV 的带隙。傅立叶变换红外光谱(FTIR)结果通过 550 cm-1 和 667 cm-1 吸收峰证实了氧化锌的合成。据我们所知,这是首次利用当地特有植物 Beaucarnea gracilis 合成氧化锌。与传统氧化锌的主要区别在于带隙从 3.3 eV 显著减小到 2.7 eV。此外,这种材料在紫外线照射下会在 530 纳米波长处发出光致发光,这归因于氧空位。紫外-可见光区域光吸收率的增加和光带隙的减小可提高基于氧化锌的太阳能电池和光催化过程的性能,从而使紫外光以外的可见光源也能使用。
