How does Rhodamine 6G work?
Rhodamine 6G is used after cyanoacrylate ester fuming. Rhodamine 6G has an affinity for adhesion to polymerized latent impressions even at levels below visual observation. Excitation of Rhodamine 6G with the 488nm, 510nm, 514.5nm or 532nm lines of the laser produces extremely bright fluorescence at about 550nm.
What color is rhodamine 6G?
Rhodamine 6G chloride is a bronze/red powder with the chemical formula C28H31ClN2O3.
What is rhodamine made of?
Rhodamine /ˈroʊdəmiːn/ is a family of related dyes, a subset of the triarylmethane dyes. They are derivatives of xanthene. Important members of the rhodamine family are Rhodamine 6G, Rhodamine 123, and Rhodamine B. They are mainly used to dye paper and inks, but they lack the lightfastness for fabric dying.
What is rhodamine soluble?
The solubility of rhodamine B in water varies by manufacturer, and has been reported as 8 g/l and ~15 g/L, while solubility in alcohol (presumably ethanol) has been reported as 15 g/L. Chlorinated tap water decomposes rhodamine B. Rhodamine B is tunable around 610 nm when used as a laser dye.
What is the chemical formula of Rhodamine B?

What color is rhodamine?
Pantone / PMS Rhodamine Red / #e60094 Hex Color Code. The hexadecimal color code #e60094 is a shade of magenta-pink.
What is the difference between rhodamine B and rhodamine 6G?
Rh. B offers a high photostable and efficient laser dye in sol–gel silica sensitized with Rh. 6G; 75,000 shots as a laser half-lifetime of the sample and 24% efficiency at pumping intensity 0.1 J/cm2 of 532 nm. Wavelength shift occurs from 606 to 630 nm in the Rh.
How toxic is rhodamine?
For Rhodamine B, the effective and lethal concentration (EC50 and LC50) –causing 50% toxicity were in the range of 14–24 mg/L. For Rhodamine WT, no statistically significant effects were observed (p<0.05) at the tsted concentrations (up to 91, 100 and 200 mg/L for algae, crustaceans and fish embryos, respectively).
