Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

435
Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.
The ATR process begins by directing a beam...

Infrared (IR) Spectroscopy: Overview

1.9K
When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.
Different compounds display unique properties due to their...

Atomic Spectroscopy: Effects of Temperature

372
Atomization, converting samples into gas-phase atoms and ions, is essential for atomic spectroscopy. The flame temperature required for atomization affects the efficiency of the atomic spectroscopic methods by increasing the atomization efficiency and the relative population of the excited and ground states.
At thermal equilibrium, the relative populations of excited and ground state atoms can be estimated using the Maxwell–Boltzmann distribution. For example, an increase in temperature...

Molecular Spectroscopy: Absorption and Emission

2.4K
Molecules possess discrete energy levels called quantum states. Unlike atoms, which have simpler energy levels, molecules possess additional rotational and vibrational energy levels.  Each energy level is separated by an energy gap, with the gaps between adjacent electronic, vibrational, and rotational levels varying significantly. The three types of energy levels in a diatomic molecule are shown in Figure 1.

¹³C NMR: ¹H–¹³C Decoupling

1.1K
The probability of having two carbon-13 atoms next to each other is negligible because of the low natural abundance of carbon-13. Consequently, peak splitting due to carbon-carbon spin-spin coupling is not observed in spectra. However, protons up to three sigma bonds away split the carbon signal according to the n+1 rule, resulting in complicated spectra.
A broadband decoupling technique is used to simplify these complex, sometimes overlapping, signals. Broadband decoupling relies on a...

    Area of Science:

    • Optics and Photonics
    • Materials Science
    • Infrared Technology

    Background:

    • Passive cooling is crucial for infrared detectors to reduce noise and improve sensitivity.
    • Existing bolometric absorbers often struggle to balance efficient absorption with minimal thermal emission, limiting performance.

    Purpose of the Study:

    • To engineer a spectrally selective bolometric absorber that decouples infrared absorption and thermal emission.
    • To enable the development of ultra-thin, passively cooled mid-wave infrared (MWIR) bolometers.

    Main Methods:

    • Utilized an antenna-coupled metal-insulator-metal resonance for MWIR photon absorption.
    • Incorporated a long-wave infrared (LWIR) optical phonon absorption feature for thermal emission.
    • Designed the structure to spectrally and spatially decouple absorption and emission phenomena.

    Main Results:

    • Achieved spectrally selective absorption in the MWIR band.
    • Demonstrated angle-dependent LWIR thermal emission via phonon resonance, minimizing interference with MWIR absorption.
    • Successfully decoupled photon detection from radiative cooling mechanisms.

    Conclusions:

    • The novel design offers a new pathway for creating ultra-thin, passively cooled MWIR bolometers.
    • Decoupling absorption and emission enhances detector performance by reducing self-heating.
    • This approach holds potential for advanced infrared sensing applications.
