ABSTRACT
GaP nanoflowers composed of numerous GaP nanowires are synthesized through heating InP and Ga2O3 powders. Crystalline GaP nanowires growing from Ga-rich particles have a cubic structure, uniform diameters of ∼300 nm, and lengths from several to tens of micrometers. Typically, an individual GaP nanowire displays a hexagonal prism-like morphology with <111> as the preferential growth direction. Cathodoluminescence measurements show that GaP nanoflowers and GaP nanowires emit at ∼600 and ∼750 nm, respectively. Additional low-intensity emission peaks are observed for GaP nanoflowers at ∼450 nm.

    We present the growth of GaAs nanowhiskers by molecular beam epitaxy on Si (111) nanowires grown by low-pressure chemical vapor deposition. The whiskers grow in the wurtzite phase, along the [0001] direction, on the {112} facets of the Si nanowire, forming a star-like six-fold radial symmetry....

    The structure of low-temperature excitonic luminescence spectra of CuBr nanocrystals of hexagonal modification is studied. It is shown that the observed spectral structure can be explained assuming the formation of exciton-phonon complexes with their subsequent annihilation and radiative...
