Monocopper Doping in Cd-In-S Supertetrahedral Nanocluster via Two-Step Strategy and Enhanced Photoelectric Response

Abstract

We apply a two-step strategy to realize ordered distribution of multiple components in one nanocluster (NC) with a crystallographically ordered core/shell structure. A coreless supertetrahedral chalcogenide Cd-In-S cluster is prepared, and then a copper ion is inserted at its void core site through a diffusion process to form a Cu-Cd-In-S quaternary NC. This intriguing molecular cluster with mono-copper core and Cd-In shell exhibits enhanced visible-light-responsive optical and photoelectric properties compared to the parent NC.

“…6b), which indicates that the SD/Ag88b possesses the best efficiency in the generation and separation of photoinduced electron/hole pairs in ITO electrodes. 47 The photocurrent density can be still ARTICLE kept after ten on/off cycles, suggesting the response reproducibility. The generation of photocurrent may involve photoinduced charge migration from S 3p to the Ag 5 s orbits.…”

Main group metal chalcogenidometalates with transition metal complexes of 1,10-phenanthroline and 2,2′-bipyridine

“…Considerable attention has been paid and substantial successes have been achieved in inorganic-organic hybrid main-group metal chalcogenidometalates. It has been revealed that the integration of organic components with inorganic chalcogenide structures can produce materials with well-defined various topological structures and hold promise for applications in ion exchange, nonlinear optics, electronics and catalysis [1][2][3][4][5][6]. According to the classification of cation components, the inorganic-organic hybrid main-group metalchalcogenidometalates can be generally divided into third categories.…”
