The fluorescent silver nanoparticles were synthesized using trisodium citrate as a reducing and stabilizing agent in a microwave-assisted reduction process. The influence of synthesizing parameters such as reaction duration, temperature, and trisodium citrate concentration (100, 200, and 400 ppm) were examined on the characteristics and fluorescent properties of synthesized silver nanoparticles (AgNPs). The formation of AgNPs was studied by UV–Vis absorption spectroscopy, X-ray diffraction, ATR-FTIR spectra, and scanning electron microscopy. The low concentration compared to the high concentration of trisodium citrate resulted in a prolonged reduction process, and also the high concentration resulted in the formation of smaller AgNPs (44 nm). The fluorescence emission spectra of the synthesized colloidal AgNPs demonstrated a quite explicit emission peak centered around 335 nm. However, the higher reaction temperature (above 100 °C) resulted in a sharp and narrow emission peak. The synthesized silver nanoparticles exhibited a suitable fluorescent property, which was reliant on the size of synthesized AgNPs.

以柠檬酸三钠为还原稳定剂，在微波辅助还原过程中合成了荧光银纳米颗粒。研究了合成参数（如反应时间，温度和柠檬酸三钠浓度（100、200和400 ppm））对合成银纳米颗粒（AgNPs）的特性和荧光性质的影响。通过紫外-可见吸收光谱，X射线衍射，ATR-FTIR光谱和扫描电子显微镜研究了AgNPs的形成。与高浓度的柠檬酸三钠相比，低浓度导致还原过程延长，并且高浓度导致形成较小的AgNP（44 nm）。合成的胶体AgNPs的荧光发射光谱显示出一个相当明显的发射峰，中心位于335 nm附近。但是，较高的反应温度（高于100°C）会导致尖锐且狭窄的发射峰。合成的银纳米颗粒表现出合适的荧光性质，这取决于合成的AgNP的大小。
