COMPOSITE FLUORESCENT GOLD NANOCLUSTER HAVING HIGH QUANTUM YIELD AND METHOD FOR PRODUCING THE SAME

摘要

To provide a composite fluorescent gold nanocluster having a high quantum yield and a method for producing the same.SOLUTION: There is provided a composite fluorescent gold nanocluster 100 comprising a gold nanocluster 110 and a capping layer 120 encapsulating at least a portion of an outer surface of the gold nanocluster. The capping layer includes a matrix 122 made of a benzene-based compound and a plurality of phosphine-based compounds 124 dispersed in the matrix.SELECTED DRAWING: Figure 1
