Quantum dots are semiconductors that are used for medical imaging, quantum computing, transistors, solar cells, LEDs, and diode lasers. It was discovered by Alexei Ekimov in the early 1980s.
Actually aluminium nitride quantum dots can be generated using a thin film growth technique and stopping the growth at the very early stages of it. Then, you can observe nano-dots on the surface that can exhibit quantum effects. You can find recent scientific articles on this link.

Nanoparticles and quantum dots are the zero dimensional structures.
The size of a quantum dot determines its bandgap, which in turn determines the color it emits. Smaller quantum dots have a larger bandgap and emit light with higher energy, appearing blue. Larger quantum dots have a smaller bandgap and emit light with lower energy, appearing red. This is due to the quantum confinement effect, where the size of the dot restricts the motion of electrons and holes, affecting the energy levels and thus the emitted color.
Yes, the dots that Roy Lichtenstein uses are his signature mark and are called 'Benday Dots'.
he uses dots :)
Solar cells have quickly become a popular for of energy research; especially solar cells known as quantum dots. Quantum dots use nanotechnology to capture light photons in larger numbers. Early research shows that quantum dots are three times more effective than regular solar cells. Also, solar cells do not contribute to pollution. These benefits make solar cells a likely form of energy harvesters in the future.
Morse code
Quantum dot absorption spectra are characterized by sharp and well-defined peaks due to the discrete energy levels of the quantum dots. These peaks correspond to the absorption of specific wavelengths of light, resulting in a unique and tunable absorption spectrum for each quantum dot.
wow. line graph.
The dots you see around Hoenn are in Braille. It's a form of writing that uses combinations of dots to represent the letters in an alphabet, commonly used by the blind to communicate.
