Transcripts - Nanotechnology: Quantum Dots
Have you ever wondered
how your TV works?
There are small particles
applied in LCD and LED
screens. Those small
particles are called
What are quantum dots?
Quantum dots are incredibly small
particles. They range between 2 to 10
nanometers in diameter. It's this small size
that gives quantum dots the unique
properties to improve our tech.
The color light that a quantum
dot emits is directly related to its
size; smaller dots appear blue,
larger ones more red.
They can be applied
in transistors, solar cells, LEDs,
and diode lasers.

One of the most promising new color enhancement technologies for
backlit LCDs is QDs, a nanocrystal material that can be tuned to emit an
optimized narrow spectrum of light.
LCD manufacturers are able to create vivid displays that can exceed 55%
of the spectrum a human eye can detect.
What are the benefits of quantum dots?
• Better colour accuracy
• Higher colour saturation
• Improved battery life
Amazon used quantum dots to good
effect in the Kindle Fire HDX 7. The
colors are excellent
Quantum Dots Can Charge Your
Smartphone In 30 Seconds
A new device by an Israeli startup
called StoreDot could revolutionize
battery charges by bringing a phone
from dead to full in about 30 seconds.
The secret to StoreDot’s technology
is quantum dots.
The “dots” are actually peptides that
have been altered to have certain
properties, like optical or the ability to
generate charge when strained.
QD have such remarkable properties that
scientists think they will soon be used in
everything from light bulbs to the design of
ultra-efficient solar cells.
Quantum dots. Sound cool, don't they? But
for once this is a technology that's actually as
good as it sounds.
