摘要：
In this work, copper silver bimetallic nanoparticles (Cu/Ag BNPs) with strong fluorescence were prepared using glutathione (GSH) as a reductant and protectant. The range of fluorescence signal of GSH-Cu/Ag BNPs to ambient temperature is 30 similar to 90 degrees C has a sensitive response and can be used as a temperature sensor. The high fluorescence intensity of GSH-Cu/Ag BNPs at around 30 degrees C indicates that the detection of Co2+ does not require harsh temperature conditions, which could be very convenient for future practical detection work. In addition, glutathione in Cu/Ag BNPs and the synergistic effect of Cu and Ag nanoparticles in Cu/Ag BNPs can be used as a metal ion sensor for Co2+ fluorescence detection.
