Surfactant encapsulating N-doped carbon dots with enhanced optical properties as a selective sensor for Cr(vi) detection

Abstract

Detecting hexavalent chromium (Cr(VI)) is important for human health and environmental protection due to its high toxicity, carcinogenicity and persistence, but developing a sensor to selectively detect Cr(VI) remains challenges....

Full-color-emitting fluids from carbon dots stabilized in nonconventionally fluorescent micelles

“…12 However, so far this strategy has not been tried in the research of R-CDs, although a few reports have appeared on solubilization of blue-emitting CDs in surfactant micelles. 13,14 We have recently reported that when a nonionic silicone surfactant (s-PTrS) was mixed with an anionic surfactant (SDS) in water, micellar solutions with bright blue emission would be obtained. 15 Adopting these micelles as the host, in this work we report the solubilization of R-CDs obtained from pyrolysis of citric acid (CA) in formamide (FA), leading to the formation of full-color-emitting colloids covering the white light.…”
