NaCl nanocrystal-encapsulated carbon dots as a solution-based sensor for phosphorescent sensing of trace amounts of water in organic solvents

Abstract

The phosphorescence of solid-state carbon dots (CDs) has been demonstrated to be susceptible to water molecules. However, solution-based CDs have been rarely exploited for phosphorescent detection of trace amounts of...

Reversible light-controlled fluorescence switch of block polymer-grafted carbon dots and cellular imaging

“…S6, ESI†), which is similar to the structure of poly(diallyldimethylammonium)-based CDs. 29 Correspondingly, the fluorescence photographs of the CD- g -poly((TPE- co -SPA)- block -NIPAM) nanoparticles dispersed in THF/water mixed solvent with different volume ratios also clearly confirm the AIE process of the TPE units during micelle formation (Fig. 4b).…”

Facile and Green Fabrication of Highly Competent Surface-Modified Chlorogenic Acid Silver Nanoparticles: Characterization and Antioxidant and Cancer Chemopreventive Potential

“…FTIR spectroscopy showed lesser stretching in AgNPs-CGA-BSA. CGA contains hydroxyl groups in its structure, which produces the characteristic fingerprint region of O–H stretching vibrations at 3138 cm –1 . − …”

“…The organic crystal structures include urea, cyanuric acid and melamine, while inorganic crystal structures include sodium chloride, sodium hydroxide, boric acid and so on. 46–48,70,72–76,78,79,82,120–130 For example, Wang et al 124 proposed a molten salt method for the preparation of CD-based RTP materials by selecting high charge density magnesium salts and phosphates as doping salts, and calcining the carbon source directly in the presence of inorganic salts (Fig. 3E).…”

“…It allows significantly increased time to visualize cell states, enables speedy detection, and also facilitates bioimaging and detection. Generally speaking, the RTP material based on CDs possesses huge application prospects in the field of anti-counterfeiting, 110,126,127,144–150 information encryption, 113,115,118,119,121,123,128,151–160 sensor detection, 114,124,129,130,147,161–174 LEDs, 175–179 biological imaging, 134,180,181 logic gates, 133 fluorescent ink 112,182–184 and other fields 116,117,122,185–195 with the properties of DF, TADF, long afterglow life and adjustable afterglow color.…”
