Description
Summary:•Metallic bismuth and aqueous sodium hypochlorite were the precursors to obtain the delta phase of bismuth oxide by LASL.•δ-Bi2O3 nanoparticle were synthetized by LASL.•Stable δ-Bi2O3 was obtained at room temperature.•Compositional, structural, and morphological features of the delta phase of bismuth oxide are reported. δ-Bi2O3 nanoparticles (NPs) were successfully synthesized by using the laser ablation of solids in liquids (LASL) technique. This is the first time, to the best of our knowledge, that the δ-Bi2O3 phase is obtained through this synthesis method. A bismuth target immersed in sodium hypochlorite as liquid medium was irradiated with a ns-pulsed Nd:YAG laser. Our results indicate that LASL is a suitable and simple technique to obtaining δ-Bi2O3.
