Abstract

In this work the optical properties of the formed gold nanoparticles, that obtained upon reducing the gold(I):6-thioguanosine hydrogel by dimethylamine borane (DMAB) have been studied. The analytical measurements to calculate the optical band gap showed a significant narrowing in the optical band gap value (E). Tauc plot was used to estimate the optical band gap (Eg) with the direct and indirect allowed transitions, before and after the reducing process. Narrowing the band gap is very important to increase the efficiency of the semiconductor material as it leads to absorbing in the visible region of the solar spectrum.

摘要

在这项工作中，研究了通过二甲胺硼烷（DMAB）还原金（I）：6-硫代鸟苷水凝胶所形成的金纳米颗粒的光学性质。用于计算光学带隙的分析测量表明，光学带隙值（E）显著变窄。在还原过程前后，使用Tauc图通过直接和间接允许跃迁来估计光学带隙（Eg）。缩小带隙对于提高半导体材料的效率非常重要，因为这会使其在太阳光谱的可见光区域产生吸收。
