Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

open access: yesAdvanced Optical Materials, EarlyView.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...

Pulsed Terahertz Attenuated Total Reflection Spectroscopy

Applied Spectroscopy, 2008
Pulsed terahertz attenuated total reflection (ATR) spectra of solid materials and liquids covering the 10 cm−1 to 120 cm−1 (0.3 THz to 3.6 THz) region of the electromagnetic spectrum are recorded using a terahertz pulsed spectrometer and silicon ATR modules. Pulsed terahertz ATR measurements are completed nondestructively using small amounts of sample

Accelerometer design based on attenuated total reflection

Applied Optics, 1988
It is shown that the effect of attenuated total internal reflection might be suitable for acceleration measurements. A prototype design and preliminary measurements are presented. The performance limitations of the device are discussed.

Simplified attenuated total reflection apparatus

Review of Scientific Instruments, 1989
We offer a version of the Kretschmann configuration of an attenuated total reflection measurement in which there is only one rotating element. Significant simplifications in construction and operation are thereby attained.

Attenuated total reflection technique

Pigment & Resin Technology, 1972
The application of attenuated total reflection (ATR) permits the use of infrared spectroscopy for the analysis of paint films. It utilises the phenomenon of abnormal dispersion close to resonance absorptions. Spectra obtained with the aid of the ATR technique are almost identical to those of the transmission method.

An attenuated total reflectance far-UV spectrometer

Review of Scientific Instruments, 2007
An ultraviolet spectrometer based on attenuated total reflection (ATR) has been developed and tested for liquid water (light and heavy water) in the wavelength range from 140to300nm, which includes the far ultraviolet (FUV) region. One of the principal limitations of FUV transmission spectra is the strong absorption of the solvent itself.

Attenuated total reflection far-ultraviolet spectroscopy

SPIE Proceedings, 2016
Recently, far-ultraviolet (FUV) spectroscopy of solid and liquid states has been a matter of keen interest because it provides new possibilities for studying electronic structures and transitions of almost all kinds of molecules. It has also great potential for a variety of applications from quantitative and qualitative analysis of aqueous solutions to

Sensor applications of attenuated total reflection infrared spectroscopy

Talanta, 2005
Attenuated total reflection Fourier transform infrared spectroscopy is one of the most powerful methods for recording infrared spectra of biological materials in general, and of biological membranes in particular. It is fast, yields a strong signal with only a few micrograms of sample and recent ATR devices allow the recording of nanogram quantities ...
