decrease in absorbance without any wavelength shifts was observed for 1, 2 and 3; represents the interaction phenomenon between DNA and its intercalator resulting from the conformational changes in DNA associated with the compounds [59]. As the concentration of CT-DNA in aqueous buffer solution ...
The wavelength of maximal absorbance or excitation for the reagent is 544 nm and its emission maximum is 576 nm, exhibiting a visual color of orange–red. Its molar extinction coefficient at 546 nm in a methanol environment is 63,000 M−1 cm−1. Other components in solution as well as...
On the shorter wavelength side, the emission and absorption processes compete, thus hampering lasing effects at this spectral region. Figure 3 (a) Emission spectra of a Rhodamine B doped microcavity for the excitation energy levels indicated in the right hand side of the graph. To make the ...
The determination of Rhodamine B (RB) dye was done on a TU-1810 UV-vis spectrophotometer by measuring absorbance at λmax of 553 nm. A calibration curve obtained at the RB dye concentration of 1–10 mg/L was used for determination of initial and final concentrations. The ...
vis absorbance spectrumof the electrode was measured by using Hitachi U-3010 UV-vis spectrophotometer. Degradation of RhB with Different Processes. Degradation of RhB was performed in a reactor with double cells (Scheme 1). A 150 mL anodic cell was placed 15 cm away from a 500W ...
Where, Ao and At are the initial absorbance and the absorbance at a given time “t” during the photocatalytic reaction of RhB, respectively. The photocatalytic degradation process was investigated as a function of several parameters such as pH effect, catalyst load, initial concentration of RhB ...
The firstrhodaminedyes absorbed relatively short wavelength light giving rise to a red color—their name stems from the Greekrhodon(rose). The high brightness and photostability ofrhodaminesmade them prominent laser dyes and many of these dye scaffolds were repurposed in the 1990s for use as antibo...
absorbance of light at a wavelength between approximately 500 and 600 nm. At these high wavelengths, there is little (if any) interference due to light scattering by the relatively small absorbance changes that can be caused by mitochondrial chromophores, e.g.,cytochromes. A single-beam ...
