However, power-law relaxation can originate from mechanisms other than diffusion. Here we report transient absorption spectroscopy measurements on CdS and CdSe nanorods recorded at temperatures ...

What is Atomic Absorption Spectrometry? AAS is a technique for determining how much of a specific element is present in the specimen under study. The uptake of optical radiation by neutral atoms in ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

Spectroscopy has been described as ‘applied quantum mechanics’ and the right spectroscopic technique can recover relatively direct information on the electronic configuration of a sample. For example, ...

Photons in the combined beam are counted by a detector. (Courtesy: Bingxin Xu et al/Nature/ CC BY 4.0 DEED) Dual-comb spectroscopy – absorption spectroscopy that utilizes the interference between two ...

For laboratories needing a high-performance flame atomic absorption (AA) spectrometer, the PinAAcle™ 900F is a flame-only system with a true double-beam design for fast start-up and exceptional ...

Edinburgh Instruments, a spectroscopy instrument manufacturer based in Scotland, launched a new benchtop system for fluorescence spectroscopy. The FS5 v2 Spectrofluorometer is suitable for perovskite ...

To test glucose levels without blood, Apple is developing a silicon photonics chip that uses optical absorption spectroscopy to shine light from a laser under the skin to determine the ...

Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...
