## Abstract CoFe~2~O~4~ hollow spheres with sizes ranging from 600 nm to 1 ฮผm were prepared through hydrothermal treatment of an aqueous solution containing glucose, ammonium iron(II) sulfate hexahydrate [(NH~4~)~2~Fe(SO~4~)~2~ยท6H~2~O], and cobalt(II) sulfate heptahydrate [CoSO~4~ยท7H~2~O], followed
Both monoclinic Ga 2 O 3 and Wurtzite-structured GaN are wide-band-gap semiconductors (energy gap, E g = 4.9 eV and 3.39 eV, respectively) that exhibit luminescence and conduction properties, thus, they have potential applications in optoelectronic devices, [1][2][3][4][5][6][7][8] high-temperature
