The obtained absorption peak can be assigned to the quantum confinement effect suggesting the formation of nanometer-size CdS particles in the as-prepared PVA/CdS nanocomposites.
In the present study we will demonstrate how the optical properties such as absorption peak position and band-width of Sm3+ ions changes from one glass host to another.
2a gives an expanded portion of the spectrum which shows the absorption peak at about 590 nm.
The absorption band in the visible light region of 350-550 nm is typical of Ag nanoparticles, because Ag nanoparticles exhibit an intense absorption peak due to the surface plasmon excitation (Fig.
The progress of the reaction was followed by measuring the decrease in intensity of the epoxide absorption peak at 915 [cm.
This strongly suggests that the pyrroles and phenyls may indeed form a large, co-planar p-[pi] conjugation, leading to a single absorption peak in visible-light range.
It is important to mention that this setup acted somehow like a resonating absorber, having the highest absorption peak around 700 Hz, thus improving the efficiency at lower frequencies.
Elaborating on the results of this study, she said:" We observed that the energy required for the electron tunneling among copper nanoparticles depends on the near infrared absorption peak and these, both, change with respect to layers copper content.
For 1, characteristic absorption peak of C=C double bond is not observed at 1401[cm.
The absorption peak at 1,050/cm for Si-O bonds disappeared after sintering the substrate at 1,650[degrees]C and 1,800[degrees]C.
The absorption peak at 334 nm is specifically the result of the tyrosine residues near the copper complex of the oxygen-bearing Hc (Hagerman 1983).
