The influence of y _ 2o _ 2s : eu phosphors fluorescent spectra, chroma and luminescence intensity is systematically studied when different concentration of europium is adulterated into different phosphors by means of xrd, fluorescent spectra analysis, time - basing spectra analysis, long - persistent fluorescent spectra analysis and so on ; the influence on y2c > 2s : eu phosphors structure, luminescence intensity and long - persistent curve is investigated when different concentration of mg24 " > ti4 " 1 " is adulterated into different phosphors, finding the most suited concentration of mg2 " * ti4 " 1 " ; base on the suited concentration of mg2 + > ti4 +, the influence rule on phosphors luminescence intensity and long - persistent curve with changing of eu + concentration is also studies. at the same time, by using rare - earths metals adulteration and theory of chroma synthesis, the possibility of sensitized buildup of phosphors and the synthesis of different color long - persistent phosphors is also researched
