【摘要】 对制备长余辉发光粉的主要影响因素进行了研究,在Al2O3与SrCO3的摩尔比为1.75 :1,激活剂Eu2+和助熔剂H3BO3的质量分数分别为1％和7％,合成温度1400℃的条件下,研 制出发射光谱波长为490nm,余辉亮度高,持续时间达10 h以上的蓝绿色长余辉发光粉.更多还原

【Abstract】 In this paper, the main factors on preparing long afterglow phosphor has been studied. When the mole ratio of A12O3 to SrCO3 is 1. 75 : 1, Eu2+ and H3BO3 content are 1% and 7% respectively, and the synthetic temperature is 1400℃ , the blue-green long afterglow phosphor can be prepared, whose emission spectrum wavelength is 490 nm, and whose afterglow brightness is high and whose duration is over 10 hours.更多还原
