Carbon quantum dots (CQDs) represent a novel class of zero-dimensional nanomaterials with exceptional optical and photocatalytic properties. This study investigates the hydrothermal synthesis of cellulose-derived CQDs, aiming to evaluate their effectiveness in degrading industrial dyes. The synthesized CQDs ...
Carbon quantum dots (CQDs) have emerged as potential alternatives to classical metal-based semiconductor quantum dots (QDs) due to the abundance of their precursors, their ease of synthesis, high biocompatibility, low cost, and particularly their strong photoresponsiveness, tunability, and stability. ...
Multicolor bandgap fluorescent carbon quantum dots (MCBF-CQDs) from blue to red with quantum yield up to 75% are synthesized using a solvothermal method. For the first time, monochrome electroluminescent light-emitting diodes (LEDs) with MCBF-CQDs directly as an active emission layer are fabricated...
emissive with a higher quantum yield. Further effort is required to understand and better control the parameters dominating the particle surface passivation and resulting properties for carbon dots of brighter photoluminescence. Generally speaking, however, the ...
found that the decoration of carbon quantum dots (CQDs) onto the surface of BiOCOOH enhanced the photocatalytic degradation of DCF via improving the charge separation. Similarly, photo- catalytic activity of g-C 3 N 4 is expected to be improved after CQDs modification. In this study, CQDs...
FIG. 9 provides plots showing electrical properties of TFTs that use SWNT network strips for the semiconductor, on thin plastic substrates. FIG. 9A shows the measured (solid dots) and simulated (open dots) influence of the width of the strips on the on/off ratio (lon/loff) and normalized...
