Enhanced photo-responsive behavior of MoS2 micro-flowers by Ag-doping

The two-dimensional material MoS2 is a promising candidate as a next-generation optoelectronic device. Pristine and Ag-doped MoS2 micro-flowers are synthesized by hydrothermal method. Both the samples show photoresponse at room temperature. Ag-doped MoS2 shows better photoresponse compared to undope...

More Information
Summary:The two-dimensional material MoS2 is a promising candidate as a next-generation optoelectronic device. Pristine and Ag-doped MoS2 micro-flowers are synthesized by hydrothermal method. Both the samples show photoresponse at room temperature. Ag-doped MoS2 shows better photoresponse compared to undoped one. The highest responsivity obtained for Ag-MoS2 is found to be around 4.3 Amp/Watt which is more than three times the value for the undoped sample. The response time for the undoped sample is 0.6 s and Ag-MoS2 is 0.9 s.
