Polymer-assisted hydrothermal synthesis of Bi2S3 nanostructured flowers

Nanostructured Bi2S3 was hydrothermally produced from Bi2O3 and thiocarbohydrazide in acidic solutions containing PVA, PEG and PVP. By using XRD, SAED and Raman spectrometry, the products were orthorhombic Bi2S3, with four vibration modes at 139.6, 253.7, 310 and 968.9 cm-1. The phase was also in ac...
