摘要
以分析纯Ｎａ＿２ＷＯ＿４为即熔剂，采用缓冷法培养出淡黄色单晶体Ｎａ＿５Ｄｙ（ＷＯ＿４）＿４。研究了该晶体的吸收光谱、荧光光谱及激发光谱。计算了它的晶胞参数：ａ＝１１．４２４Ａ，ｃ＝１１．３３５Ａ。并确定了Ｄｙ￣（３＋）的能级，为进一步研究其激光性能提供必要的数据基础。
Transparent light yellow single crystals,Na_5Dy(WO_4)_4,were grown by the slow ccoling method。Theresults of X-ray diffraction analysis show that crystals belong to the space group A with lattice parameters a= 11.424A,e=11.335A.The absorption,fluorescence,excitation and infrared spectra of such crystals were measured and analyzed at room temperature,and at the same time,the energy level of ion was given, These result,provide experimental basic for the study of lase properties of Na_5Du(WO_4)_4crystals。
