The idea of using quantum dot as a light source first developed in 1990s.

These did not use quantum dots, but had a number of features in common with them.

The potential benefits of the quantum dot approach has led to widespread research in the field.

That's the whole point of using quantum dots in lasers.

Quantum dots also require very little power since they are not color filtered.

One system under investigation for this is quantum dots.

The islands can be subsequently buried to form the quantum dot.

The coloration is directly related to the energy levels of the quantum dot.

Quantum dots are in fact often referred to as artificial atoms.

That is, a large fraction of the atoms in the quantum dot are on the surface.

Quantum dots and fluorescent beads are usually considered for this purpose.

A blue quantum dot is just slightly above the minimum size, where red to green can be easily obtained.

More recently the Kondo effect has been observed in quantum dot systems.

They also hope to produce solar powered displays using quantum dots.

Then again, only little is known about the excretion process of quantum dots from living organisms.

The downside, however, is that quantum dots are usually made of quite toxic elements.

The method consists of building quantum dots using aluminum islands.

Size and band gap are inversely related in quantum dots.

The glimmer of utility on the horizon are things called quantum dots.

Steve Ross A quantum dot is just a very small piece of material.

These fluorophores are either small molecules, protein or quantum dots.

The ability to tune the size of quantum dots is advantageous for many applications.

Starting from early 2000, scientists started to realize the potential of developing quantum dot as the next generation light source and display technology.

For comparison, the wavelength emitted by the quantum dots was around 900nm.

Some quantum dots are small regions of one material buried in another with a larger band gap.
