摘要

采用溶剂热法合成了核壳结构纳米荧光粉GdF

：Ce

，Dy

@GdF

：Eu

。XRD衍射图样显示所制备纳米晶为正交相；在Ce

的

7/2

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。

Abstract

The core-shell structure nanophosphors GdF

:Ce

@GdF

:Eu

were synthesized

via

solvothermal method. XRD patterns show that the synthesized nanocrystallines(NCs) are orthorhombic phase both for the core and shell. Under the excitation of

7/2

of Ce

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.
