Description
Summary:Tin sulfides are promising materials in the fields of photoelectronics and photovoltaics because of their appropriate energy bands. However, doping in SnS<sub>2</sub> can improve the stability and robustness of this material in potential applications. Herein, we report the synthesis of SnS<sub>2</sub> nanoflakes with Zn doping via simple hydrothermal route. The effect of doping Zn was found to display a huge influence in the structural and crystalline order of as synthesized SnS<sub>2</sub>. Their optical properties attest Zn doping of SnS<sub>2</sub> results in reduction of the band gap which benefits strong visible-light absorption. Significantly, enhanced photoresponse was observed with respect to pristine SnS<sub>2</sub>. Such enhancement could result in improved electronic conductivity and sensitivity due to Zn doping at appropriate concentration. These excellent performances show that Sn<sub>1&#8722;<i>x</i></sub>Zn<i><sub>x</sub></i>S<sub>2</sub> nanoflakes could offer huge potential for nanoelectronics and optoelectronics device applications.
