Synthesis and optical absorption investigation on GaP/GaN core/shell nanocomposite materials

In this paper, two-step solvothermal method was adopted to synthesize GaP/GaN nanocomposite materials. The core/shell structure formation was characterized by X-ray powder diffraction pattern (XRD) and high-resolution transmission electron microscopy (HRTEM). Meanwhile, optical absorption spectra showed distinct blue shift compared with GaP nanometer materials, which indicated that GaP/GaN core/shell nanometer heterostructures appeared to be formed.
