title: The synthesis of BaMgAl10O17:Eu2+ nanorods and their luminescence properties under UV and VUV excitation.
abstract: BaMgAl10O17:Eu2+ nanorods were synthesized by the sol-gel process at 1,250 degrees C, while bulk phosphor was prepared by conventional solid-state reaction at 1,600 degrees C. The naonrods had a homogeneous grain size 80-100 nm in diameter and 0.8-1 microm in length. Under 254 nm excitation, the emission intensity of these nanorods was 90.12% of the commercial phosphor. Under 147 nm excitation, the intensity rate was 78.15%. The color coordinates were (0.145, 0.062) under ultraviolet (UV) excitation and (0.143, 0.068) under VUV excitation. Compared with the standard blue fluorescence (0.14, 0.08), the y value was obviously decreasing. These low y values suggested that these BAM nanorods were good for restricting the decrease of BAM effciency during heating.
