Luminescence properties of individual BN-coated CaS:Eu nanowires have been studied by high-spatial-resolution cathodoluminescence (CL) spectroscopy. A broad red light-emitting band from an individual nanowire has been observed. Detailed local CL studies on the nanowires reveal spatial variations of luminescence from the structure surfaces toward their cores. Such variations are attributed to the different Eu(2+) ions surroundings within the surface and core nanowire regions. The attractive luminescence properties are meaningful for fundamental studies of nanoscaled luminescent materials and may be of interest for novel optoelectronic applications.
