摘要
A new solid state synthesis method, called the high temperature ball milling (HTBM) method, was developed for the production of high performance single phase BaMoO4:Eu3+ phosphor powders. In this work, X-ray diffraction (XRD) and scanning electron microscope (SEM) techniques and emission spectra test were used to characterise the obtained phosphor powders. Compared with chemical precipitation method often employed for the synthesis of phosphors interested, the HTBM method not only decreased the solid synthesis temperature from 1000 to 600°C, but also enhanced the emission intensity of yielded phosphors in the red light region by 48%. Additionally, BaMoO4:Eu3+ red phosphor powders produced by the HTBM method have relatively small and more uniform particle sizes. The HTBM method thus opens a new path to solid state synthesis, especially for the materials difficult to obtain at low temperature.
