Long lifetime pure organic phosphorescence based on water soluble carbon dots.

چکیده
Carbon dots show potential in lighting and displays. However, only their fluorescence has been observed so far. Here we report the observation of phosphorescence from carbon dots in a polyvinyl alcohol matrix. The phosphorescence is attributed to C=O bonds on the surface of carbon dots and has a very long lifetime (~380 ms).

Dual-emissive Polymer Dots for Rapid Detection of Fluoride in Pure Water and Biological Systems with Improved Reliability and Accuracy.
It is of paramount importance to develop new probes that can selectively, sensitively, accurately and rapidly detect fluoride in aqueous media and biological systems, because F(-) is found to be closely related to many health and environmental concerns. Herein, a dual-emissive conjugated polyelectrolyte P1 containing phosphorescent iridium(III) complex was designed and synthesized, which can fo...
متن کاملSynthesis of high-quality carbon nanodots from hydrophilic compounds: role of functional groups.
A simple one-pot hydrothermal approach has been demonstrated for the preparation of highly water soluble and photoluminescent carbon nanodots (C-dots) from low-cost organic compounds. We found that the compounds incorporating amino and carboxylic acid groups are suitable for the preparation of highly photoluminescent and water-soluble C-dots.
متن کاملIntermolecular Electronic Coupling of Organic Units for Efficient Persistent Room‐Temperature Phosphorescence
Although persistent room-temperature phosphorescence (RTP) emission has been observed for a few pure crystalline organic molecules, there is no consistent mechanism and no universal design strategy for organic persistent RTP (pRTP) materials. A new mechanism for pRTP is presented, based on combining the advantages of different excited-state configurations in coupled intermolecular units, which ...

متن کاملEvaluation of organic carbon, elemental carbon, and water soluble organic carbon concentration in PM2.5 in the ambient air of Sina Hospital district, Tehran, Iran
In the present study, carbon species including organic carbon (OC), elemental carbon (EC), and water-soluble organic carbon (WSOC) concentration in PM2.5 were assessed at an urban site of Tehran, Iran during March to June 2014. The PM2.5 samples were collected using an frmOMNITM Ambient Air Sampler. Thermal gravimetric analysis (TGA) was used to analyze OC and EC. The results showed that PM2.5 ...
