摘　　要：硒锗钠(Na2Ge2Se5)是一种极具潜质新型红外非线性材料。但该化合物具有明显的制备难点。根据其制备特点,自行设计并搭建反应装置,高效、安全制备其前驱体Na2Se;然后将制备的Na2Se与Ge、Se按化学计量比称取,在单温区合成炉中合成Na2Ge2Se5多晶料。对制备的Na2Se、Na2Ge2Se5多晶进行XRD,SEM、EDS等分析测试表明产物为高纯单相Na2Se、Na2Ge2Se5多晶。Na2Ge2Se5is one of the new infrared nonlinear optical materials with potential applications.However it is very difficult to prepare. Based on the properties of the compound,a new reactor was designed and built to synthesize Na2 Se efficiently and safely. Then the prepared Na2 Se and Ge,Se were weighed in stoichiometric ratio to synthesize Na2Ge2Se5 in a single zone furnace. The synthesized Na2 Se and Na2Ge2Se5 were tested by XRD,SEM and EDS,the results show that both the two products are high pure and single phase.
