    Multicomponent nanoheterostructure containing upconverting materials and semiconductor nanocrystals have been a growing interest in recent years. An interaction between these components can improve the existing and induce new materials and electronic properties. Here, we reported the synthesis of new nanoheterostructure consisting of NaYF<inf>4</inf>:Yb,Er decorated with AgInS<inf>2</inf> nanocrystal via a thermal decomposition reaction. The NaYF<inf>4</inf>:Yb,Er were used as seed crystal of the synthesis of NaYF<inf>4</inf>:Yb,Er/AgInS<inf>2</inf> nanoheterostructure. The results of combine upconverting and semiconducting materials indicate that the NaYF<inf>4</inf>:Yb,Er/AgInS<inf>2</inf> nanoheterostructure shows photoactivity under NIR irradiation. Compared with pure AgInS<inf>2</inf> nanocrystal, the nanoheterostructure of NaYF<inf>4</inf>:Yb,Er/AgInS<inf>2</inf> exhibits a strong light absorption characteristics in visible region, which more effective than that of pure AgInS<inf>2</inf> nanocrystal.
