Due to strong photoluminescence,extraordinary photostability,excellent biocompatibility,and good water-solubility,metal nanoclusters have attracted enormous attention since discovered.They are found to be novel fluorescence labels for biological applications and environmental monitoring.Recently the chemiluminescence(CL) or electrochemiluminescence(ECL) of metal nanoclusters has received increasing attention.This review covers recent vibrant developments in this field of the past 5 years,and highlights different functions of metal nanoclusters in various CL and ECL systems,such as luminophores,catalysts,and quenchers.Latest synthetic methods of metal nanoclusters used in CL or ECL are also summarized.Furthermore,we discuss some perspectives and critical challenges of this field in the near future.
Due to strong photoluminescence, extraordinary photostability, excellent biocompatibility, and good water-solubility, metal nanoclusters have pointed to be novel fluorescence labels for biological applications and environmental monitoring. Recently, the chemiluminescence (CL) or electrochemiluminescence ECL) of metal nanoclusters has received fresh attention. This research covers recent vibrant developments in this field of the past 5 years, and highlights different functions of metal nanoclusters in various CL and ECL systems, such as luminophores, catalysts, and quenchers. Most recently synthetic methods of metal nanoclusters used in CL or ECL are also summarized. Futurerther, we discuss some perspectives and critical challenges of this field in the near future.
