inorganicorganic hybrid nanoparticles between phosphotungstic acid (PTA) and rhodamine 6G (R6G) were synthesized by mixing a solution of 0.1 mmol R6G in ethanol (40 mL) and 40 mL of aqueous solution of PTA (0.2 g). The as-prepared PTA-R6G nanoparticles were characterized by scanning electron microscopy (SEM), UV-vis spectra, and Fourier transform-infrared (FT-IR) spectra. The SEM studies show that the PTA-R6G nanoparticles have an average diameter of about 111 nm and the atomic ratio of W to P is 12.7:1, near to the chemical stoichiometry of PTA. UV-vis spectra confirm that the R6G aggregates formed in PTA-R6G nanoparticles are J-type. The Keggin structure of PTA is maintained in the PTA-R6G hybrid nanoparticles, as demonstrated by FT-IR.
