Significats de optical absorption en anglès

This study complements previous UOT experiments that demonstrated optical absorption contrast.

Results: We found that the speckle-free feature of PAT results directly from the optical absorption contrast.

We propose a method to use acoustic spectra of photoacoustic signals to quantify the absolute optical absorption.

Methylene blue accumulation in SLNs was confirmed photoacoustically by using the optical absorption spectrum of the dye.

Using optical -resolution photoacoustic microscopy, we quantified the absolute optical absorption of black ink samples with various concentrations.

Photoacoustic (PA) microscopy (PAM) can image optical absorption contrast with ultrasonic spatial resolution in the optical diffusive regime.

Moreover, the effective masses of the carriers are relatively light, and the optical absorption coefficients are high under visible illumination.

We circumvent this requirement by quantifying the optical absorption coefficients from the acoustic spectra of PA signals acquired at multiple optical wavelengths.

Effective optical absorption and efficient separation of photogenerated charge carriers are among the key factors for achieving high efficiency in a photocatalytic process.

Theoretical modeling of the MoS 2 optical absorption spectra with and without the applied electric field provides quantitative support for the proposed mechanism.

Optical -resolution photoacoustic microscopy (OR-PAM) becomes a premier microscopic imaging tool in biomedicine because it provides agent-free optical absorption information in tissues.

All compounds displayed excellent thermal properties and an appropriate alignment of energy levels for the perovskite with maximum optical absorption in the near-UV region.

Complementary ab initio calculations reveal that these materials have disorder-tunable optical absorption, large dielectric constants, and electronic bandgaps that are relatively insensitive to disorder.

We have developed a dual-modality imaging system by integrating optical -resolution photoacoustic microscopy and fluorescence confocal microscopy to provide optical absorption and fluorescence contrasts simultaneously.

Different analytical techniques such as scanning electron microscopy, glancing angle X-ray diffraction, Rutherford backscattering spectrometry and optical absorption have been used to study the structures.

The nature of the very intense optical absorption, which is caused by Mn(2+) doping and determines the colour of the material, is discussed.
