Since the optoelectronic devices consist multicomponent interfaces, the synthesis of nanoparticles and fabrication of devices play a significant role in quality, cost, and fast fabrication of devices. The wet chemical synthesis holds the great promise of controlling of these factors. Herein, we have developed a wet chemical method for the synthesis of one-dimensional Bi2S3 nanoflakes and demonstrated its photoresponsivity by fabricating prototype device by dry-casting of Bi2S3 suspensions on the electrodes. A key advantage of the present approach is the synthesis and fabrication were carried out in the ambient conditions. (C) 2017 Elsevier Ltd. All rights reserved.
