Figure 2From: Integrated nanophotonic hubs based on ZnO-Tb(OH)3/SiO2 nanocomposites ZnO nanotip adhering to a Tb(OH) 3 /SiO 2 . (a) An electron beam was focused at a point (white dot) on the ZnO nanowire, which was grown on a Tb(OH) 3 /SiO 2 nanosphere with an acceleration voltage of 10 keV. (b) Collected CL spectrum of (a). The inset is the CL spectrum of pure ZnO nanowires.Back to article page
