Ce~(3+)和Y~(3+)掺杂对Ca_2MgSi_2O_7:Eu~(2+)荧光粉发光性能的影响

在还原气氛下,采用高温固相法合成了Ca_2MgSi_2O_7:Eu~(2+),Rs~(3+) (R~(3+)=Ce~(3+),Y~(3+))系列荧光粉.结果表明,少量稀土离子的掺入没有改变晶体的物相结构.在Ca_2MgSi_2o_7:Euz~(2+)荧光粉中,Ce~(3+)和y~(3+)的掺入对荧光强度的影响较大,且与掺杂元素、掺杂量相关.当掺杂Ce~(3+)和Y~(3+)的量分别为0.007mol和0.05mol时,所得荧光粉在532nm处的发光强度分别是未掺杂时的127%和117%.结果表明,在Ca_2MgSi_2O_7中Ce~(3+)与Eu~(2+)存在能量传递,Ce~(3+)的加入显著敏化了Eu~(2+)的发光,导致荧光强度的进一步提高;Y~(3+)的掺杂可以使荧光粉的粒径减小,并导致基质中的电荷缺陷而敏化Eu~(2+)发光,从而使荧光强度进一步提高.
