| 中文摘要 | we report a direct one-pot approach, employing tetrakis(hydroxymethyl)phosphonium chloride (thpc) and 11-mercaptoundecanoic acid (11-mua) as combined reducing/capping agents, for the rapid preparation of fluorescent gold nanoclusters (auncs) from haucl4 in aqueous solution at room temperature. the as-prepared auncs exhibit a fluorescence emission at 535 nm, a quantum yield of 1.8% and average diameters of 2.0 +/- 0.5 nm. the resultant mua/thpc-auncs have been exploited, for the first time, for the highly sensitive and selective detection of silver ions (ag+) in aqueous solution when using edta as a masking agent for hg2+. the fluorescence intensity quenches linearly within the range of 25 nm to 3 mu m with high sensitivity (lod = 9 nm, s/n = 3) and this sensing system has been applied for environmental water sample analysis. |
