Pesticides widely used in modern agriculture can impact on the environment and human health and hence it is important to develop highly sensitive detectors for pesticide residues. Optical methods based on photoluminescence (PL) properties provide an ideal approach to facile and accurate trace-level analysis of pesticides. Carbon Quantum Dots (CQDs) have been proposed as the photo-sensitizer for this...
Monodispersed water-soluble fluorescent carbon nanoparticles (CNPs) were synthesized directly from glucose by a one-step alkali or acid assisted ultrasonic treatment. The CNPs were characterized by transmission electron microscopy, optical fluorescent microscopy, fluorescent spectrophotometry, fourier transform infrared spectrophotometry and ultraviolet-visible spectrophotometry. The results showed...
