Absorption and emission spectra of rhodamine 6G (R6G) are reported in mixed solutions of dodecyltrimethylammonium bromide (DTAB) with various polyelectrolytes, including the sodium salts of poly(acrylic acid) (PAA), poly(methacrylic acid) (PMA), poly(styrenesulfonic acid) (PSS), polygalacturonic ...
TRITC also is more stable to photobleaching than FITC (Section 1), and its absorption and emission spectra are less sensitive to environmental conditions, such as pH. It is best, however, to use only fresh reagent for modification purposes. Storage should be under desiccated conditions, protected...

Rhodamine dyes are often used as scaffolds in biological labeling and turn﹐n fluorescence imaging. To date, their absorption and emission spectra have been expanded to the entire near﹊nfrared region (6500 nm), which provides a more suitable optical window for monitoring biomolecular production, ...

ganglia cells has been done successfully which proves the probe could be further applied for biological applications. An another rhodamine based probe was developed byAlam et al.[6]for specific CHEF based enhancement in absorption and emission for detection of trivalent metal ions such as Al, Fe ...
Absorption and emission spectra of RHB (2 ppm), RHBAcylCl (7 ppm), 1 (3 ppm), 2 (5 ppm) & 3 (4 ppm) in acetonitrile solutions are shown in Fig. 4 and the corresponding photophysical properties of especially 1, 2 & 3 are summarized in Table 1. Optical density of all the solutio...
