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
應用x射線粉末衍射( xrd ) 、熒光光譜、時間分辨光譜及磷光體長余輝壽命測試等綜合實驗手段,較系統地研究了摻雜eu對熒光體y2o2s : eu熒光體的發光光譜、色度和發光強度的影響;研究了不同mg , ti含量對磷光體基質結構性能、發光強度與余輝曲線的影響及其適宜的摻雜濃度;基此,研究了在給定mg , ti含量時,不同eu摻量對磷光體發光強度和余輝的影響規律;從稀土摻雜和色度合成原理分別探討了eu的發光敏化增強和制備不同光色長余輝磷光體的可能性。
