摘要： BaMgAl_{10}O_{17}:Eu^{2+}, known as BAM, is a very important blue-emitting phosphor used in plasma display panels (PDP) and three band fluorescent lamps. In this paper, the Ba_{0.85}MgAl_{10}O_{16.94} :Eu^{2+}_{0.09} phosphors with different fluxes (BaF_2, MgF_2, AlF_3, BaCl_2, MgCl_2, AlCl_3, H_3BO_3) were prepared by high temperature solid-state reaction method and the influence of different fluxes on the luminescence of Ba_{0.85}MgAl_{10}O_{16.94}:Eu^{2+}_{0.09} phosphor was studied under 254nm excitation and vacuum ultraviolet (VUV) excitation. It was found that fluorides have better flux effects than chlorides and H_3BO_3. The mechanism of particle growth in the presence of flux in the process of phosphor preparation is discussed in detail. Particle size distribution and the crystal structure of the phosphors are also analysed.

It was found that fluorides have better flux effects than chlorides and H$_3$BO$_3$. The mechanism of particle growth in the presence of flux in the process of phosphor preparation is discussed in detail.
