[The preparation of electric arc method and spectral analysis on long persistence luminescent chinaware of SrAl2O4:Eu2+].
Luminescent chinaware of long persistence of SrAl2O4:Eu2+ has been prepared with using are method. Fluorescence and excitation spectra were measured in order to study its luminescence and long persistence properties. Results show that both of luminescent chinaware and polycrystalline powdered phosphor are the same in luminescence decay and consist of an initial fast process and a later extremely slow process. Long persistence properties of luminescent chinaware are better more than polycrystalline powdered phosphor, and its function of environment-resistant has been improved prominently.
