  1. We researched the influences of systhesis temperature, heat preservation time, eu + concentration, reduction surrounding feeling and flux on luminescent properties of sral2o4 : eu2 + phosphors, optimized the experiment conditions and reduced systhesis temperature about 100 c. we found that the systhesized sample ' s luminescent brightness is better with increasing systhesis temperature, but the phase component is more complex. we found that the luminescence brightness of sample appear a increasing process at first, and then a reducing one with the raise of eu2 + concentration, it indicated that the luminescence brightness is not better if the eu2 + concentration is too high or low. we found that the systhesized sample can not bright at too long heat preservation time, and the luminescence brightness is lower at too short heat preservation time. we found that particle diameter is bigger, the wavelength of emission peak is longer

    研究發現合成溫度高,合成樣品的發光效果好,但物相組成也較復雜; eu ~ ( 2 + )離在一定摻雜濃度范圍內,合成樣品的發光亮度先是出現一個提高過,然後是一個降低過,說明eu ~ ( 2 + )離濃度高或低都不利於合成樣品發光;保溫時間較長,合成樣品不發光,保溫時間較,合成樣品發光效果不好,只有合適的保溫時間才能合成發光效果好的樣品;合成樣品的徑大小與發峰的位置具有一定的關系,徑越大,發峰越偏向長波方向;助熔劑對樣品的合成溫度和發光性能都有影響,助熔劑的量較低時,主要表現為助熔作用,對發光影響不大,助熔劑的量較高時,使得樣品發光亮度降低和余輝時間縮;還原方式的不同,合成樣品的發光性能也不一樣。
