激发峰激发下,该核壳结构具有明显的多色发光性能,而在相应的非核壳结构中却由于Ce

共掺导致Eu

出现荧光猝灭现象。基于CIE坐标,可以看出该体系的核壳结构具有比非核壳结构优越的发光性能,这主要是因为Gd

起到媒介离子的作用。最后,讨论了壳厚度对发光的影响,结果发现当核壳的量比为1:3时,荧光粉具有最大的发光强度。

the core-shell structure nanophosphors exhibit well multicolor luminous performance
while for corresponding none core-shell structure nanophosphors
emission of Eu

denotes obvious fluorescence quenching phenomenon due to co-doping Ce

. Based on the CIE(

) coordinate diagram
it can be seen that the core-shell structure nanophosphors own more excellent luminescent properties than that of the none core-shell structure nanophosphors due to the influence of Gd

. Lastly
the influence of thickness of shell on lighting of the phosphors was discussed. It is found that the core-shell structure phosphors own the best emission intensity on condition that ratio of the core and shell is 1:3.
