2019年8月5日 · In this article, we fabricated p-type bismuth oxide (Bi2O3) thin films with tailoring optical band gap by boron (B) doping, for the first time. In addition, an effort is made to see the influence of B doping on the surface morphological, structural, optical and electrical transport properties of Bi2O3 thin films.

A new and simple method of biosynthesis assisted by tannic acid (C76H52O46) is used to obtain bismuth trioxide nanoparticles Bi2O3 in which the β-Bi2O3 phase is identified. Synthesis takes place at room temperature and atmospheric pressure from the reduction of bismuth nitrate pentahydrate (Bi(NO3)3·5H2O) in solution, using tannic acid as a ...
