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。Drupal ' s captcha module adds a very simple math test to the comment form to add another level of complexity to thwart spam - bots
也就是說，除了讓使用者會誤以為自己是色盲的圖形驗證碼之外，可以改用數學小測驗來分辨人或機器。
