摘要：

Investigation on the basic properties and dielectric behavior of Bi2S3 nanorods will open up new areas of applicability of bismuth sulfide nanostructures. In this paper, Bi2S3 nanorods with good crystallinity have been synthesized using bismuth nitrate and thiourea by forced condensation method at 180 degrees C. The structural and morphological studies reveals the formation of distinct uniform nanorod like morphology, passing high aspect ratio, polycrystalline nature and growth along the orthorhombic (310) axis. The pre-pared Bi2S3 nanorod samples possess very good dielectric properties. The results obtained reveal that properly oriented nanorods exhibit a high dielectric constant and a small dielectric loss. The dispersion of relaxation time at higher temperature was investigated through the cole-cole analysis and reported here. (C) 2022 Elsevier B.V. All rights reserved.
