研究了Zn(NO3)2·6H2O、CO(NH2)2、R-C6H4-SO3N a、Eu2O3和L iN O3为原料,通过均匀沉淀法制备了Eu3+、Li+共掺杂的纳米ZnO材料,并通过改变Li+的掺杂比例来研究纳米氧化锌基材料的发光性能,用XRD、紫外和荧光等分析手段对样品进行表征。结果表明:制得的纳米粉体粒径在50nm左右,引入L i+后增强了纳米ZnO∶Eu3+材料的紫外可见光吸收和红色发光性能,且与L i+的掺杂浓度有关,当L i+∶Eu3+的摩尔比为0.6时,其在601nm处的特征峰最强。
The Zn (NO3) 2 · 6H2O, CO (NH2) 2, R-C6H4-SO3Na, Eu2O3 and LiN O3 were used as raw materials. Eu3 + and Li + codoped ZnO were prepared by homogeneous precipitation method. The doping ratio of Li + was used to study the luminescent properties of ZnO nanomaterials. The samples were characterized by XRD, UV and fluorescence spectroscopy. The results show that the particle size of the prepared nano-powder is about 50nm, the UV-visible absorption and red emission of nano-ZnO: Eu3 + are enhanced by the introduction of L i +, which is related to the doping concentration of L i + The molar ratio is 0.6, the characteristic peak at 601 nm is the strongest.
