For chiral plasmonic nanomaterials, as shown in Fig.2c, the resonant plasmonic coupling between individual nanoscale building blocks results in the appearance of bisignated CD signals in the spectral region of plasmon resonances, which is also known as exciton coupled circular dichroism (ECD)105. Fo...
Light emitters, also known as light sources, are essential optical components for the construction of display systems. In general, a compact form factor is in high demand with the development of wearable devices; however, conventional systems are still bulky because several ROEs and DOEs are requir...
Light-dependentresistorscan be classified into two types based on the materials used to construct them: Intrinsic photoresistors: These are made of pure semiconductor materials such as silicon or germanium. They have a large band gap and require high-energy photons to excite electrons across it. T...
IR spectroscopy as a generic analytical technique may particularly benefit from the discussed advanced MIR light sources. By default, IR spectroscopy is based on broadband thermal infrared radiation. For target application scenarios, these may be replaced by non-coherent yet better tailorable IR light ...
In addition, high power lasers can increase the temperature of protective materials, which is a crucial factor in their failure. High-intensity light sources, such as sky lanterns and spotlights, are increasingly used in daily life, which results in a series of problems63. Currently, the technol...
radiation (sunlight) and is therefore a natural source of radiation energy invisible to the human eye that propagates at the speed of light and in straight paths. As the earth's atmosphere absorbs most of the space (solar)UV radiation, any UV application is based on man-made UV sources. ...
Eighteen firefly species found in the U.S. and Canada are classified as threatened, meaning scientists have determined they are at high risk of extinction within the next 10 years or so, according to arecent comprehensive assessment. And that number may be an undercount. Researchers didn't have...
suppliers offer a variety of lamp design and engineering options, as well as custom solutions for challenging configurations. Collaborating with an experienced UV lamp supplier like LightSources ensures that your UV lamps deliver optimal disinfection with maximum energy efficiency, resulting in cost ...
Perovskite LEDs (PeLEDs) that operate at room temperature have already been developed5, opening up the path for practical perovskite-based light sources. These devices have the potential to be a game changer in fields such as next-generation displays6, general-purpose lighting7 and optical ...
as anthocyanins21,22. Zhang et al.21summarize the effects of light quality and intensity on gene expression and metabolite accumulation, while Hashim et al22highlight the use of artificial light sources to elicit SM production in in vitro cultured medicinal plants. However, these reviews have not...
