제목 CsPbBr3 Perovskte Quantum Dots/Cellulose based Colorimetric Sensor Fabrication
초록 Here, we propose a simple and portable cellulose-based colorimetric sensor integrated with CsPbBr3 PQDs for the rapid naked-eye detection of chlorine and iodine ions. We synthesized the CsPbBr3 PQDs/cellulose composite via a hot injection method, which allows the formation of monodispersed CsPbBr3 PQDs with high sensitivity; given the strong adherence of the CsPbBr3 PQDs to the porous cellulose fibers, the composite exhibited excellent stability and durability against various humidity conditions along with superior photoluminescence properties. When applying our CsPbBr3 PQDs/cellulose composite as an early diagnosis sensor, we observed a remarkable color change at a fast rate after the introduction of the sample solution, resulting from its rapid diffusion into the porous cellulose network, that could be quantified via red, green, and blue imaging analysis.
