Ratiometric fluorescent sensors for nitrite detection in the environment based on carbon dot/Rhodamine B systems

A novel carbon dot/Rhodamine B-based ratiometric fluorescent probe was developed for a highly sensitivity and selective detection of nitrite (NO(2)(−)). The probe showed colour changes from blue to orange under ultraviolet light in response to NO(2)(−) with a detection limit as low as 67 nM in the r...

description A novel carbon dot/Rhodamine B-based ratiometric fluorescent probe was developed for a highly sensitivity and selective detection of nitrite (NO(2)(−)). The probe showed colour changes from blue to orange under ultraviolet light in response to NO(2)(−) with a detection limit as low as 67 nM in the range of 0 to 40 μM. A ratiometric fluorescent test paper was successfully prepared using the probe solution, which demonstrated its feasibility towards a rapid and semi-quantitative detection of NO(2)(−) in real samples.
