Abstract 1D metal‐oxide nanostructures have attracted much attention because metal
oxides are the most fascinating functional materials. The 1D morphologies can easily …

The pathway towards the realization of optical solid-state lasers was gradual and slow. After
Einstein's paper on absorption and stimulated emission of light in 1917 it took until 1960 for …

Catalyst-free pn homojunction ZnO nanowire (NW) arrays in which the phosphorus (P) and
zinc (Zn) served as p-and n-type dopants, respectively, have been synthesized for the first …

We report white light-emitting diodes fabricated with ultrasmall CdSe nanocrystals, which
demonstrate electroluminescence from a size of nanocrystals (< 2 nm) previously thought to …

The excitonic light emission of ZnO films have been investigated by means of
photoluminescence measurements in ultraviolet-visible region. Exciton confinement effects …

We utilized a thermal radiation method to synthesize semiconducting hollow ZnO
nanoballoons and metal-semiconductor concentric solid Zn/ZnO nanospheres from metallic …

Unlike conventional bulk or film materials, one-dimensional (1D) semiconducting zinc oxide
(ZnO) nanostructures exhibit excellent photoelectric properties including ultrahigh intrinsic …

Zinc oxide (ZnO) is a potential candidate material for optoelectronic applications, especially
for blue to ultraviolet light emitting devices, due to its fundamental advantages, such as …

“Efficiency droop,” ie, a decline in brightness of light-emitting diodes (LEDs) at high electrical
currents, limits the performance of all commercial LEDs and has limited the output power of …

In the past two decades, semiconductor quantum dots and wires have developed into new,
promising classes of materials for next‐generation lighting and display systems due to their …
