“…Deconvolution of the N1s spectra (Fig. 2d) disclosed the presence of pyridinic and pyrrolic nitrogen at 399.0 and 399.8 eV, respectively [35]. Examination of XPS and FTIR analysis con rms the existence of nitrogen, carbon, oxygen, and hydrogen-containing functional groups bonded on the surface of CDs, encompassing hydroxyl, carboxyl/carbonyl, amide, and amine moieties.…”

The growing interest in carbon dots (CDs) arises from their diverse applications and unique properties. This study addresses challenges in CDs for photodetector (PD) applications, specifically surface defects and trap states hindering efficient charge transport. CDs/P3HT composites were prepared to overcome these issues by incorporating CDs in a poly(3-hexylthiophene) (P3HT) matrix. Broad absorption in spectroscopic characterization revealed its utility in fabricating a broadband PD. The CDs/P3HT PD displays a remarkable broadband photoresponse, spanning both UV and visible regions. The CDs and P3HT are effectively combined via non-covalent π-π interactions constituted by their conjugated systems. The π-π interaction increases electron delocalization and facilitates efficient charge transfer due to band alignment at the junction interface. Hence, fabricated CDs/P3HT PD demonstrated enhanced photocurrent compared to pure CDs, exhibiting high responsivity of 6.12×10-3 AW-1 and detectivity of 0.69×109 Jones. This study highlights the potential of CD/P3HT composites for broadband photodetector applications with enhanced photoelectric conversion.

One-step microwave synthesis of red-emissive carbon dots for cell imaging in extreme acidity and light emitting diodes

Abstract: Highly acid-sensitive R-CDs were obtained via a microwave method. The relationship between the FL emission and the surface groups of the R-CDs was studied in detail. The R-CDs were used for cell imaging in extreme acidity and fabrication of red LEDs.
