Current studies have shown that QDs can be effectively employed as FRET and/or eT donors to dye molecules in QD-dye conjugate systems, with outstanding optical properties of QDs including narrow and symmetric emission and broad absorption spectra for multicolor signal or imaging.

2014年7月22日 · Energy transfer from quantum dots (QDs) to variable-length, dye-labeled peptides is reported. We find that existing models used to calculate the efficiency of energy transfer from steady-state measurements are insufficient for nanoparticle–dye interactions.

2008年8月28日 · Here we consider these properties in a comparison of organic dyes, which are the most versatile molecular labels, with QDs made from II/VI and III/V semiconductors, which are the most frequently...

2023年1月1日 · Coupling of-COOH functionalized QDs with dye results in decreasing fluorescence intensity and lifetimes of QDs analogous to quenching mechanism. The observed enhancement in acceptor intensity is essentially due to dipole–dipole interaction confirming energy transfer and its dependence on spectral overlap.

2023年1月25日 · QD–dye systems are promising models for artificial photosynthesis and down-converter systems for LEDs and displays. To better understand the factors controlling energy transfer from the QDs to the dyes, we fabricated a series of Cd x Zn 1–x S/ZnS quantum dot (QD)-perylene diimide (PDI) composite nanocrystals.

2023年11月20日 · Fluorescence resonance energy transfer (FRET) based on quantum dots (QDs) and dye molecules have great application potential in biochemical fields. How to achieve an efficient energy transfer process has become an important research topic.

2024年10月29日 · Quantum dots (QDs) are semiconductor nanocrystals whose optical properties can be tuned by altering their size. By combining QDs with dyes we can make hybrid QD-dye systems exhibiting energy transfer (ET) between QDs and dyes, which is important in sensing and lighting applications.

1 天前 · The comparison of degradation efficiency for different cells at 0.8 V in Fig. 8 c shows that the introduction of ZnS QDs greatly benefits the degradation of MB dye, and TiO 2 /CZS/6ZnS cell exhibited the highest efficiency of 89 % comparing to 59 % for TiO 2 and 78 % for TiO 2 /CZS cell after 3-hour degradation.

We observe ∼78% degradation efficiency for MB and ∼48% for MO in dye concentrations of 10 mg/100 ml. A colorimetric detection method was used to real-time detection of degradation efficacy. The obtained results indicated that QDs decorated 3D printed system can be a significant system for wastewater treatment. 1. INTRODUCTION.

2024年3月28日 · Here, we probe the ET from single lead halide perovskite QDs, capped by alkylphospholipid ligands, to organic dye molecules employing single-particle photoluminescence spectroscopy with single-photon resolution. We identify a Förster-type ET by spatial, temporal, and photon–photon correlations in the QD and dye emission.
