Herein, planar p-i-n type perovskite solar cells (PSCs) with enhanced efficiency and long-term stability were developed by incorporating CQDs into a nickel oxide (NiO) hole transport layer (HTL). The incorporat
(PL) emission andoptical properties, easier to synthesize at large-scale with low cost, as comparable toquantum dots. CarbonQuantum Dotscomponents and structure determine their diverse characteristics. Most of the carboxyl moieties on the surface of the CQD gives a great solubility in water and ...
Carbon quantum dots (CQDs) as a new class of emerging materials have gradually drawn researchers' concern in recent years. In this work, the graphitic CQDs are prepared through a scalable approach, achieving a high yield with more than 50%. The obtained CQDs are further used as structure-...
Strategies for selectively imaging and delivering drugs to tumours typically leverage differentially upregulated surface molecules on cancer cells. Here, we show that intravenously injected carbon quantum dots, functionalized with multiple paired α-carboxyl and amino groups that bind to the large neutral ...
microwave pyrolysis has a distinct disadvantage that the incident energy is not directly transferred to the carbon precursor. Thus C-QDs often have an amorphous structure and poor photostability. Recently, our group reported the synthesis of excitation independent C-QDs; however, the synthesis process...
Synthesis of short-chain passivated carbon quantum dots as the light emitting layer towards electroluminescence Short-chain passivated fluorescent carbon quantum dots (S-CQDs) with graphitic structure were synthesized via a one-step hydrothermal approach using phthalic acid with a benzene ring conjugated ...
One-step uniformly hybrid carbon quantum dots with high-reactive TiO2 for photocatalytic application High-reactive facets dominated anatase TiO2 is of great significance to solve environment and energy challenges. Maintaining the pristine structure and imp... W Wang,Y Ni,Z Xu - 《Journal of Alloys...
regarded as carbon nanodots. Carbon nanodots (CNDs) therefore can be seen as quasi-spherical carbon nanoparticles with amorphous structural core distinct from the carbon quantum dots. In a nut shell, the crystal structure of the carbon core differentiates CNDs andCQDsbut that is scientifically ...

13. However, the quantum yield of c-dot 2000 was 3.5%, indicating a clear correlation between the purity of carbon dots and their quantum yield15. It is important to note that the quantum yield value is influenced by the surface structure of the carbon dots and potential modifications made ...
