Effect of Adsorption Characteristics of Rhodamine 6G Dye Solution in Fe₃O₄ Magnetic Nanoparticles on Fluorescence Quantum Yield

Figure 2

Absorbance spectra of 3.0 µM rhodamine 6G mixed with four different dosages of Fe₃O₄ magnetic nanoparticles. The treatment time is 0 min, as a representative sample. a, b, c, and d represent Fe₃O₄ magnetic nanoparticles dosages of 2.5, 5.0, 7.5, and 10.0 mg/L, respectively. Absorbance peak exists at 525 nm.
