The combined materials create a tuned system that can be adjusted to allow light only of certain specific wavelengths
because the material naturally works at near-infrared wavelengths, this could enable new avenues for infrared spectroscopy,
Unlike most of the commercially available detectors, RAPID can spot photons (light particles) of both visible and infrared light (wavelengths from 0. 4. 6 micrometres.
the increased spectral coverage means that far more photons can be gathered, especially from infrared wavelengths, where many objects shine most brilliantly.
Scientists also can make them glow at certain wavelengths and tune them to release the drugs in the presence of the cellular environment.
and manipulate light at scales much smaller than the wavelength of the light is said very difficult
because the light from a typical laser contains exactly one color, a specific wavelength of the electromagnetic spectrum, rather than a broad-range of different wavelengths.
White light is viewed typically as a complete mixture of all of the wavelengths of the visible spectrum, said Ning,
To produce all possible wavelengths in the visible spectral range you need several semiconductors of very different lattice constants
lasers have been able to emit every single wavelength of light except for white. The problem is that typical lasers only beam one specific wavelength of light at a time.
To create white the ASU researchers manufactured three thin semiconductor lasers each as thick as one-thousandth of a human hair
These molecules give off a certain wavelength when put under infrared light beams, which will be placed in the car.
it releases heat at a specific wavelength of infrared light that passes easily through the atmosphere and out into space.
it radiates the heat as infrared light of 10 micrometer wavelength. Since nothing in the atmosphere can absorb that,
