Preparation of GaP/RhB nanocomposite by ultrasonic irradiation

The GaP/rhodamine B (RhB) nanocomposite was synthesized by ultrasonic irradiation method and characterized by transmission electron microscope, Fourier transformation infrared spectroscopy and Raman spectroscopy. The results show that the morphology of GaP/RhB nanocomposite changed from “superlattice” to asymmetric core-shell and finally to symmetric core-shell microstructure with the extending of irradiation time. The possible reason for the changing of morphology of GaP/RhB nanocomposite was investigated.
