White tuning allows users to change the
color of light from warm to neutral to cool in appearance.
Ask: What
color of light reflects off the blue surface in the diagram?
Unlike the fluorescent colors of quantum dots, the colors emitted by the new carbon dots depend on the
color of light that the researchers use to excite them.
It does what a cloud does optically--that is, it changes the intensity and
color of light. It's made of about five hundred feet of theater gels in eleven different colors, all crumpled up and held together by superstrength clothespins of my own design.
Lasing materials can be crystals, gases or semiconductor (diode) materials, each determining a unique wavelength or
color of light emitted from the laser.
A typical laser produces one
color of light with superb precision.
Each component is designed to absorb a different
color of light, with the top, middle, and bottom segments capturing blue, green, and red light, respectively.
Models based on this picture successfully predict the intensity and
color of light emitted by a variety of atoms in the sun's chromosphere.
