摘要
研究了铝酸锶铕长余辉荧光粉配制时激活剂Eu2+掺量，P2O5,B2O3及添加剂A掺量，煅烧温度，还原气氛，冷却工艺，粉磨细度等对光强的影响荧光衰减曲线用I=I1exp(-x/t1)+I2exp(-x/t2)+I3exp(-x/t3)拟合。
In this paper the influence of the stimulant Eu2+ concentiation, P2O5, B2O3 the mole concentration thedrop of additive A, calcining temperature, adducing atmosphere, Cooling rate and grinding fineness etc. on the luminous intensity is studied when 4 (Srl-xEux ) 0.7Al2O3·nB2O3·yP2O5 steady persistence fluorescent material wasmade . The decay curve was fit with I = I1 exp(- x/t1 ) + I2exp(- x/t2) + I3exp(- x/t3). Three different lifetimes were found.
