Tubular Co3O4 nanostructures were prepared from cobalt nanowires embedded in an anodic alumina template.The morphologies of nanowires / nanotubes were studied b
We investigate the spectroscopic properties of the 1.53-μm emission from the 4I13/2 → 4I15/2 transition of Er3+ions in Al(PO3)3-based fluorophosphate glass fo
High quality epitaxial GaN films on (0001) sapphire substrates were grown by a commercial metal-organic chemical vapour deposition system. The, etch pits and th
A nanocrystalline model for microstructures of liquid metals is constructed. According to the nanocrystalline model, the intensity curves of x-ray diffraction (
