Eu^sup 3+^ doped Gd^sub 2^O3 nanotubes have been synthesized using multi wall carbon nanotubes as removable templates by employing a liquid phase deposition method. The prepared Eu^sup 3+^ doped Gd^sub 2^O3 nanotubes were characterized by means of x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy, fourier transform infrared sepctroscopy and thermogravimetry and differential thermal analysis. XRD patterns conrm the cubic phase of Eu^sup 3+^ doped Gd^sub 2^O3 nanotubes. From the measured SEM images, the average diameter of the Eu^sup 3+^: Gd^sub 2^O3 nanotubes were estimated to be in the range of 50â[euro]"70 nm. The photoluminescence analysis revealed that the Eu^sup 3+^: Gd^sub 2^O3 nanotubes can display a strong red emission peak at around 616 nm, due to the ^sup 5^D^sub 0^â[dagger]'^sup 7^F^sub 2^ electric dipole transition of Eu^sup 3+^ ions. Such luminescent powders are expected to find potential applications in fluorescent lamps and display device applications.[PUBLICATION ABSTRACT]
