For starters, the bandage's not - so - secret key ingredient is phosphors — molecules that absorb light and then emit it via a process known as phosphorescence.

Light - emitting diodes (LEDs) made from semiconductor materials are already used in traffic lights because they last for years and use a fifth of the electricity of normal light bulbs, but they tend to emit blue light that must be converted to white, an inefficient proLight - emitting diodes (LEDs) made from semiconductor materials are already used in traffic lights because they last for years and use a fifth of the electricity of normal light bulbs, but they tend to emit blue light that must be converted to white, an inefficient prolight bulbs, but they tend to emit blue light that must be converted to white, an inefficient prolight that must be converted to white, an inefficient process.

Stars are glowing balls of gas that through atomic processes release energy that is emitted as light and heat.

Yet so far, star formation historians have mostly relied on other indicators to write their histories: light at a particular frequency that is typically emitted when giant clouds collapse, heating up in the process and radiating away that heat in the form of specific spectral lines.

Light tuned to a particular frequency causes the system to jump from a low - energy to high - energy state, or vice versa, absorbing or emitting a photon, or particle of light, in the proLight tuned to a particular frequency causes the system to jump from a low - energy to high - energy state, or vice versa, absorbing or emitting a photon, or particle of light, in the prolight, in the process.

Hubble captures something close to real colors, but in similarly processed images from the infrared Spitzer Space Telescope, all stars appear blue (because stars emit more light at visible wavelengths and in the near - infrared).

To figure out which frequency of ultrasound would be most efficient for water purification, the scientists looked at another process related to cavitation called sonoluminescence, in which water bubbles bombarded with sound actually emit light.

So thirsty are theorists for new insights into black holes and relativistic processes that, with each LIGO detection, observational astronomers have leapt into action to target those enormous patches of sky, hoping to see some afterglow or other emission of electromagnetic radiation — even though by definition the resulting larger black hole should emit no light.

But one problem is that dark excitons do not emit light, making it hard to determine their spins and use them for quantum information processing.

From 240 miles above Earth's surface, lightning is visible as bright blotches, and city lights appear as yellow streaks; the atmosphere glows in bands of yellow, green, and red as energetic air molecules interact and emit light, a process (called airglow) that is difficult to see from the ground.

The proof - of - concept device, which has been presented today, 3 May, in IOP Publishing's journal Semiconductor Science and Technology, takes advantage of the latest nano - scale materials and processes to emit green and red light separated by a wavelength of 97 nanometres — a significantly larger bandwidth than a traditional semiconductor.

It aims to detect the neutron's presumed EDM by looking for changes in the light emitted when cold neutrons interact with helium - 3 nuclei in the presence of an electric field, a process that is subtly altered if the neutron has an EDM.

The new plasmonic material, can be applied to both polymer light - emitting diodes (PLEDs) and polymer solar cells (PSCs), with world - record high performance, through a simple and cheap process.

Semiconductors emit light when bound pairs of electrons and holes, known as excitons, recombine in a process called radiative decay.

It is known, that quantum - dot based LEDs, or QLEDs, can suffer from «droop,» or reduced efficiency, at high pumping intensity due to processes that dissipate the energy of excitons before they have time to emit light.

You can observe this process happening everyday inside of a fluorescent lamp, when a UV light excites chemicals coating the inside of the bulbs to emit visible light.

Sadly, our eyes weren't made to process the harsh blue light that most electronics (like your lap top) emit.

The process works by emitting a low - powered infrared laser light that is cool to the touch and virtually painless.

The processes (absorption of light, collisional energy transfer and emission) can be separated because the average time that an isolated CO2 molecule takes before it emits a photon is much longer that the time for collisional de-excitation (~ tens of microseconds at atmospheric pressure, less, higher in the atmosphere).

«In the process of undergoing these nuclear fusion reactions, the sun emits large amounts of heat and light.

He primarily serves clients who are developing new products such as organic light - emitting diodes, medical and drug - delivery devices, chemical processes, high - performance materials, beverage additives, plastics, and polyester additives.

CMEL said it used low - temperature poly - silicon thin film transistor (LTPS TFT) process technology from its mates at Chi Mei Optoelectronics (CMO) together with its own organic light - emitting diodes (OLED) to develop its 25 - incher.
