Abstract 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$_3$BO$_3$) 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$_3$BO$_3$. 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.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
