Sentence examples for main absorption peak from inspiring English sources

As the plasma power was increased, the contact angle, refractive index, and main absorption peak of thin films were increased while the optical transmittance was decreased, signifying that the plasma-polymerized organic films have more low surface energy with increasing RF power.

Analysis of the XPS-spectra indicates that polymer films can be deposited if the F/C ratio of the starting fluorocarbon molecules is smaller, or close to 3. FTIR-absorption spectra of films on Si wafers show an "amorphous" film structure with the main absorption peak of CF2-groups at 1200 cm−1.

It has been reported that the main absorption peak at 664 nm corresponds to the n-π* transition of MB [26, 27].

In aqueous medium, MB exhibits a main absorption peak at 664 nm with a shoulder at 614 nm as shown in Figure 8.

It can be seen that the main absorption peak of RhB gradually shifted from 552 to 537 nm, corresponding to the stepwise formation of a series of N-de-ethylated intermediates.

At pH = 4.0 in the range of 350 550 nm, no main absorption peak was observed but a main absorption peak appeared about 373 nm when pH increased from 4 to 10 indicating the formation of ZnO nanoparticles. it was observed that higher pH (pH 8) enhances the rate of reduction as the colour of the solution turned colloidal brown more quickly compared to a solution of lower pH (Fig. 1).

The main absorption peaks in the electronic spectra of SOEK are gradually red-shifted with the extended conjugation.

Infrared spectroscopy showed nearly the same main absorption peaks of neat nylon 6 and samples from nylon 6/spandex fabrics.

In addition, upon doping, the color of the polymer films changed significantly with the main absorption peaks bathochromically shifted from the visible to near-infrared region.

The main absorption peaks of solutions and films of the copolymers are at 354 nm and 347 nm, respectively, showing the combined contribution from the 3,6-carbazole and fluorene blocks.

The study of optical properties of GeSe NBs shows that the main absorption peaks are modulated by side passivation of the terminators, and quantum yields of side passivated GeSe NBs are evidently bigger than those of pristine ones mainly because passivated ones have suitable band gap values.
