Semiconducting nanowire heterostructures are of particular interest because of their fascinating properties and potential applications in the field of nanoscale science. CdS, with a direct bandgap of 2.42 eV, is considered to be an excellent material for various optoelectronic applications
Lu Kong et al.
Journal of nanoscience and nanotechnology, 12(11), 8258-8265 (2013-02-21)
Quantum dots are being widely used in physics and in the biomedical industry in recent years due to their excellent optical characteristics. However, studies have shown that cadmium selenide core-shell quantum dots exhibit cytotoxicity. The present study investigates the induction

Optics express, 21 Suppl 1, A15-A22 (2013-02-15)
Ultrafast time-resolved absorption spectroscopy is used to investigate exciton dynamics in CdSe nanocrystal films. The effects of morphology, quantum-dot versus quantum-rod, and preparation of nanocrystals in a thin film form are investigated. The measurements revealed longer intraband exciton relaxation in

Physical review letters, 110(18), 180404-180404 (2013-05-21)
Quantum confinement can dramatically slow down electron-phonon relaxation in nanoclusters. Known as the phonon bottleneck, the effect remains elusive. Using a state-of-the-art time-domain ab initio approach, we model the observed bottleneck in CdSe quantum dots and show that it occurs

The CdS/SiO(2) core/shell nanowires (NWs) with controlled shell thickness were successfully synthesized and subsequently heat-treated at 500 °C. The influences of silica shell coating and annealing processes on their optical properties have been investigated. Compared with original CdS NWs, the
