Synthesis of highly luminescent graphitized carbon dots and the application in the Hg2+ detection

One‐pot synthesis of carbon dots using two different acids and their respective unique photoluminescence property

“…FWHM is often taken as an indicator of the distribution of the origin of the luminescence (12). The scanning electron microscopy results supported this from a morphological point of view, where the C-dots produced from H 3 PO 4 showed very homogenous distribution in terms of morphology compared with those synthesized from H 2 SO 4 (Fig.…”

Carbon Based Dots and Their Luminescent Properties and Analytical Applications

“…The detection limit of the method was 0.1 µM. Up to now, various sensors for Hg 2+ based on CDs have been fabricated with signal-off process [93,98,115,138,155,167,[223][224][225][226][227]. Most of the experiments were designed reasonably, and the results were good.…”

“…13). Since then, ethylene glycol, bovine serum albumin, hair and ethylenediaminetetraacetic acid (EDTA) have also been dehydrated by concentrated H 2 SO 4 to prepare various kinds of CDs [167][168][169][170]. However, the dehydration reactions were usually carried out with heating assistance (from 40 to 200°C).…”

Highly fluorescent carbon dots for visible sensing of doxorubicin release based on efficient nanosurface energy transfer

“…Numerous natural and synthetic, graphite and organic substances have been explored for the fabrication of CDs with various routes, such as oxidization by-products of carbon nanotubes and graphite (Tao et al 2011) and candle soot (Liu et al 2007), hydrothermal cracking or microwave assisted synthesis of organic compounds (Sahu et al 2012;Yang et al 2012). Due to their unique properties, CDs have increasingly shown potential in broad applications including energy conversion , environmental analysis and bioanalysis (Costas-Mora et al 2014;Liu et al 2012), sensors (Gao et al 2014), diagnostics (Posthuma-Trumpie et al 2012) and bioimaging (Wang et al 2014a, b).…”
