Simulation of quantum dots (QDs) in the confinement regime

International Journal of Applied Science and Engineering Research, 2012
The ground state confinement energy and its associated wavelength as a function of radius for three different semiconductor quantum dots (QDs) were calculated using the Brus equation. The experimental observation of the size dependence on the band gap energy is in good agreement with the theoretical models for the semiconductor nanocrystals considered.

Current Application of Quantum Dots (QD) in Cancer Therapy: A Review

Mini-Reviews in Medicinal Chemistry, 2017
Semiconductor quantum dots proved themselves as efficient fluorescent probes in cancer detection and treatment. Their size, high stability, non-photobleaching and water solubility made them a unique fluorophore in place of conventional organic dyes.Newly emerged theranostic drug delivery system using quantum dots helped us in better understanding of ...

Applications of quantum dot (QD) lasers in optical communications for datacenters

2017 19th International Conference on Transparent Optical Networks (ICTON), 2017
Optical communication technologies are the best solutions for the high-performance computing infrastructures (HPCs) and datacenter networks (DCNs). All-optical approach consists of switching all data at the packet in the optical domain which requires data rates higher than 100 Gbit/s.

Synthesis of CdTe colloidal quantum dots (QDs) in water

Frontiers of Chemistry in China, 2008
The comparison of growth processes and fluorescent properties of CdTe semiconductor quantum dots (QDs) that are synthesized in water with different modifiers are discussed in this paper. The samples are characterized through ultraviolet-visible spectra (UV-Vis), photoluminescence spectra (PL) and zeta potential.

Improving the performance of quantum dot light-emitting diodes by tailoring QD emitters

Nanoscale, 2023
As the emitters of quantum dot light-emitting diodes, quantum dots, which are responsible for the charge injection, charge transportation, and especially exciton recombination, play a significant role in quantum dot light-emitting diodes.

Subcellular Distribution of CdSe Quantum Dots (QDs) in Breast Cancer Cells

Journal of Nanoscience and Nanotechnology, 2012
In spite of great advances in conventional cancer diagnosis and treatment, the early recognition and characterization for various cancers remain a technological bottleneck. The combined characteristics of board absorption and narrow emission make quantum dots (QDs) desirable fluorescent labels for cancer imaging and other applications in the biomedical

Quantum Dots (QDs) Based Fluorescent Sensor for the Selective Determination of Nimesulide

Journal of Fluorescence, 2013
Fluorescent PET (Photoinduced Electron Transfer) has been of particular growth in recent times. A novel PET based fluorescent sensor using unmodified CdSe quantum dots (QDs) has been developed for the trace determination of Nimesulide (NIM). The sensor is based on the selective fluorescence quenching of quantum dots by NIM in presence of other NSAIDs ...

Quantum dots (QDs) based fluorescence probe for the sensitive determination of kaempferol

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2014
In this work, using the quenching of fluorescence of thioglycollic acid (TGA)-capped CdTe quantum dots (QDs), a novel method for the determination of kaempferol (KAE) has been developed. Under optimum conditions, a linear calibration plot of the quenched fluorescence intensity at 552nm against the concentration of KAE was observed in the range of 4 ...

Quantum Dot (QD) Fluorochromes for Exploration of Nanocompartments in Living Cells

Biomedical Optics, 2006
Photostable, highest emission QD fluorochromes are introduced for enzyme-organelle studies in nanocompartments of living cells. Progress towards intracellular localizations is foreseeable using high-resolution digital photography applied to genomics, proteomics, diagnostics-prognostics, and drug trials.
