The direct observation of a substantial bandgap increase compared to bulk hematite is revealed. This finding shows that these low-dimensional nanomaterials may be used for the generation of hydrogen by solar illumination without applied bias.L. Vayssieres...
that could potentially enable tailoring of the quantum-confined Stark effect (QCSE). The QCSE arises when a quantum-confined system is subjected to an electric field applied along the axis of confinement. For semiconductor quantum wells, the applied field skews the potential...
Combining quantum confinement effect with halide compositional stoichiometry engineering can potentially realize light emissions covering the whole visible range. Bright and uniform photoluminescence (PL) from four different kinds of PeQWs under ultraviolet (UV) irradiation (365 nm) are demonstrated in Fi...
The one-dimensional quantum-confinement effect in α-Fe 2 O 3 ultrafine nanorod arrays is studied. The formation of bundles of ultrafine hematite nanorods is understood by considering the crystal structure of ΒFeOOH, which occurs in nature as the mineral akaganeite. Every third layer is only ...

The extent of the confinement depends upon the size of the particle, so changing the size of the particle changes its properties in a predictable way. This effect can be used to tune the band gap of the semiconductor so that dots emit different colours of light when illuminated by ...
Quantum dots advantages over traditional nanomaterials are due to quantum confinement effect, which bring broad absorption spectra, superior brightness and durability for different applications. The most important factor in developing nano carriers for biological applications is the toxicity, so...
