Polyvinyl pyrrolidone (PVP), playing roles as a templating agent, can be applied to prepare blue-emitting copper nanoclusters (Cu NCs@PVP) on the basis of a rapid chemical reduction synthesis method. The Cu NCs@PVP displayed a blue emission wavelength at 430 nm and the corresponding quantum yield (QY) could reach 10.4%. Subsequently, the as-synthesized Cu NCs@PVP were used for the trace analysis of furaltadone based on the inner filter effect (IFE) between Cu NCs@PVP and furaltadone, which caused the fluorescence to be effectively quenched. Additionally, this proposed determination platform based on the Cu NCs@PVP for furaltadone sensing possessed an excellent linear range from 0.5 to 100 μM with a lower detection limit of 0.045 μM (S/N = 3). Meanwhile, the Cu NCs@PVP also could be applied for the sensing of temperature. Furthermore, the practicability of the sensing platform has been successfully verified by measuring furaltadone in real samples, affirming its potential to increase fields for the determination of furaltadone.
聚乙烯吡咯烷酮（PVP）作为模板剂，可应用于快速化学还原合成法制备蓝色发射铜纳米团簇（Cu NCs@PVP）。Cu NCs@PVP 发射出 430nm 的蓝色荧光，相应的量子产率（QY）可达 10.4%。随后，基于 Cu NCs@PVP 和呋喃它酮之间的内滤效应（IFE），将合成的 Cu NCs@PVP 用于呋喃它酮的痕量分析，使荧光有效猝灭。此外，基于 Cu NCs@PVP 的呋喃它酮传感测定平台具有从 0.5 到 100μM 的优异线性范围，检测限低至 0.045μM（S/N=3）。同时，Cu NCs@PVP 也可用于温度传感。此外，通过测量实际样品中的呋喃它酮，成功验证了传感平台的实用性，证实了其在呋喃它酮测定领域的应用潜力。
