Controllable preparation of Cs + incorporated polyacrylonitrile (PAN) gel for rapid and highly sensitive visual detection of Pb 2+
Abstract
The pollution of lead poses significant environmental and health risks. A luminescent perovskite-based gel sensor was developed for rapid and highly sensitive visual Pb 2+ detection, which facilitates the conversion of Pb 2+ into luminescent CsPbBr₃ nanocrystals. This approach offers significant potential for real-time environmental monitoring and heavy metal analysis.
