Photo-responsive Bi < inf > 2 < /inf > S < inf > 3 < /inf > nanoflakes: Synthesis and device fabrication at ambient conditions

Abstract

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 photo-responsivity 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.
