Its convert‑UV‑photon‑to‑heat cycle happens fast: It takes roughly ten-trillionths of a second for a molecule of oxybenzone to get back to the way it was. 2 This means that one molecule of ...

Figure 1: An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by ...

Often times some spots on a print need a little bit of extra UV to firm up. [Mile] has set out to create an open-source UV curing wand named Photon that is cost-effective and easy to build.

Photon sieves are engineered to see in extreme ultraviolet (EUV), which has shorter wavelengths and higher energy than other types of ultraviolet light. Today's sun observatories, such as the ...

Vacuum Ultraviolet source for testing luminescence, LED lighting and photo-excited spectroscopy. Ultraviolet Excitation system provides ready access to vacuum-ultraviolet (VUV) for material analysis, ...

“However, by using a UV-shielding encapsulant layer in perovskite solar cells, the UV photon of the solar spectrum will be lost, hence limiting further efficiency gains.” ...

Anycubic Photon Mono X works with an 8.9-inch 4K monochrome LCD screen for UV-sensitive resin printing. Combined with a sizeable arm and build plate, this machine has a total build area of 7.56 ...

Photon upconversion (UC) could be the key to solving this problem. It is the process of converting long-wavelength, low-energy photons (such as those present in visible light) to short-wavelength, ...
