Abstract：

Poly　(N-vinyl-2-pyrrolidone)-capped　CdS　nanocrystals　with　different　crystalline　sizes　were　synthesized　through　a　simple　solvothermal　method.　The　structures　of　the　as-synthesized　samples　were　characterized　by　XRD,　N　2　physisorption,　TEM,　IR　spectroscopy,　and　UV-Vis　spectroscopy.　The　results　show　that　the　as-synthesized　samples　are　poly　(N-vinyl-2-pyrrolidone)-　capped　CdS　nanohybrid　materials;　the　grain　size　of　CdS　nanocrystals　is　smaller　when　tetramethylammonium　hydroxide　(TMAH)　is　introduced　in　the　reaction　system.　In　addition,　it　is　also　found　that　the　bandgap　of　CdS　nanocrystals　is　blue　shifted　and　the　visible-light　photocatalytic　activity　of　the　sample　synthesized　in　the　presence　of　TMAH　increases　due　to　the　size　effect.
