摘要:
采用水热法合成了NaGd(MoO4)2: Tb3+, Eu3+荧光粉。利用X射线衍射(XRD)对样品进行了测试,所制样品的衍射峰与标准卡片PDF#25-08282一致。样品的发光性质通过激发光谱和发射光谱进行了表征。证实了从Tb3+到Eu3+有能量传递的存在。
Abstract:
Tb3+, Eu3+ codoped NaGd(MoO4)2 phosphors were prepared by the method of hydrothermal pro- cess. The structure of the phosphors was characterized by the X-ray diffraction (XRD), which was corresponded to JCPDS card with # 25-0828. The photoluminescence properties of the prepared products were characterized by the excitation and emission spectra. The energy transfer from Tb3+ to Eu3+ in NaGd(MoO4)2 phosphors was confirmed.
