Overall, the results of this recent study highlight the potential of quantum dots based on ZnSe and ZnS for developing blue light-emitting laser technologies with low toxicity.

It proposes a liquid-based laser system that utilizes flowing quantum dots and emits blue, red, and green light. This laser ...

Quantum dots patterned using heat instead of UV light Laser heating creates fine patterns of quantum dots for high-resolution color displays by Prachi Patel, special to C&EN ...

Engineers have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays. The size determines color, but all the pyramid-shaped quantum dots ...

The monochromatic laser light stimulated the three different CQDs to re-emit light of red, green, and blue wavelengths. They applied a filter to remove most of the light from the original laser ...

A Thousand Dots Of Light May 29, 2002, 10:19am ... however, can be problematic. Each dye molecule requires a laser of the same color to ... and they change to a red or blue color to indicate the ...

Test number 1 - is the blue laser just one wavelength? (essentially) The laser lists the wavelength at 405 nm. Shining it through my spectral glasses produces a series of blue dots.

Coat a blue LED with a thin layer of microscopic beads called quantum dots of a particular size and the resulting hybrid LED gives off white light, similar to that produced by an incandescent lamp.

Armed with blue, green and red lasers, physics professor and blogger Rhett Allain walks through some curious interactions between light and matter.
