6nm)对新型蓝光发射长余辉材料Sr2MgSi2O7∶Eu2+(0·2%),Dy3+(8%)进行了光谱研究。
3.
Afterglow property of long afterglow phosphor Sr_2MgSi_2O_7∶Eu~(2+),Dy~(3+) and the influence of Dy~(3+) on its afterglow time;
利用溶胶-凝胶法制备了蓝色长余辉材料,在紫外光激发下,发射出较强的蓝光,峰值位于464 nm,来源于Eu2+的4f65d1→4f7的宽带发射;通过对2个样品热释光及余辉衰减曲线的比较,发现Dy3+的掺入在基质中产生了更密也更深的陷阱,使得材料的蓄光性能大大增强,从而起到了延长余辉的作用。
2)  long afterglow materials
长余辉材料
1.

补充资料:余辉
分子式:
CAS号:

性质:燃烧停止或移开点火源之后,材料的持续辉光。通常,辉光是指一种无焰的燃烧现象。是材料燃烧过程中的一个阶段,也是评价材料燃烧行为的一个指标。例如,材料在进行垂直燃烧检验时,除了记录余焰时间外,还要求记录余辉时间,并把它作为材料阻燃分级的依据之一。
