Abstract

$Ga_2O_3$ nanobelts were synthesized from mechanically ground GaN powders with a thermal annealing in a nitrogen atmosphere. The nanobelts are with the range of about $10{\sim}200nm$ width and $10{\sim}50nm$ thickness. Three different ZnO nanomaterials (nanobelts, nanorods, and nanowires) were synthesized at three different substrate temperatures from the thermal evaporation of ball-milled ZnO powders at $1380^{\circ}C$. In cathodoluminescence(CL), the peak energy of near band-edge(NBE) emission was determined for nanobelts, nanorods, and nanowires.
