摘要：

In order to avoid the impurity phase, such as Ag3SbS3 and Sb2S3 among AgSbS2 particles and simplify the complicated steps in synthesizing AgSbS2 via conventional methods, the cubic AgSbS2 silk-like nano flowers with well-defined crystalline structure were synthesized by the one-step, facile and practical solvothermal chemical process. The results show that the as-prepared stoichiometric AgSbS2 nano flowers with the diameter of 1 mu m are comprised of silk-like ultrathin nanoflakes. Moreover, the possible formation mechanism of AgSbS2 silk-like nanoflowers with PSS (poly (sodium-p-styrenesul-fonate)) is studied. Furthermore, the AgSbS2 nanoflowers exhibit a broad absorption and high value of incident photon to current conversion efficiency (IPCE) in visible light range, indicating that it is a promising photovoltaic absorption material.
