Visible–infrared two-dimensional Fourier-transform spectroscopy [PDF]

Optics Letters, 2002
We report on a new class of optical multidimensional Fourier-transform spectroscopy associated with a visible excitation-infrared emission configuration, in which the emitted field results from second-order optical nonlinearities. This configuration is demonstrated on a phase-matched sample of known nonlinear response by coherent measurement of the mid-

Fourier Transform Infrared Emission Spectroscopy of Si ii 

Physical Sciences Forum
Accurate and precise spectral data for singly ionized silicon (Si ii) are important for numerous applications. In this work, we present high-resolution Fourier transform IR emission spectroscopy of Si ii, using spectra recorded with the 1 m FTS at the ...

Hydration of mixed halide perovskites investigated by Fourier transform infrared spectroscopy

APL Materials, 2019
The mixed lead halide perovskites are promising candidates for solar cells, but the intrinsic instabilities due to phase segregation, halide migration, and hydration hinder the practical applications.

Far infrared fourier transform spectroscopy of semiconductors [PDF]

Mikrochimica Acta, 1987
Fourier transform spectroscopy (FTS) is one of the most important tools in the study of shallow level donors and acceptors in semiconductors. When combined with a two-step photothermal ionization process detected photoconductively, FTS allows measurement of optical transitions of donor-bound electrons (and acceptor-bound holes) in ultra-pure germanium ...

FTIR Microspectroscopy Coupled with Two-Class Discrimination Segregates Markers Responsible for Inter- and Intra-Category Variance in Exfoliative Cervical Cytology. [PDF]

, 2008
Infrared (IR) absorbance of cellular biomolecules generates a vibrational spectrum, which can be exploited as a “biochemical fingerprint” of a particular cell type.
