微波诱导燃烧法制备LaBO_3:Eu,Gd粉体及其表征
|
摘要
以水合硝酸镧(La(NO_3)_3·nH_2O)为氧化剂,甘氨酸(C_2H_5NO_2)为还原剂,无水碳酸钠(NaCO_3)为助熔剂,掺杂氧化铕(Eu_2O_3)和氧化钆(Gd_2O_3)粉体,通过微波诱导燃烧法合成LaBO_3:Eu,Gd荧光材料。研究了Eu、Gd的掺杂量、微波功率、焙烧温度和时间等工艺参数对合成LaBO_3:Eu,Gd的影响。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、红外光谱(FT-IR)、紫外-可见漫反射光谱(UV-Vis DRS)和荧光光谱(PL)等分析手段对所制粉体进行表征。结果表明:当Eu的掺杂量为2%,Gd掺杂量为3%,微波功率350 W,焙烧温度500℃,焙烧时间3 h时,制得的LaBO_3:Eu,Gd粉体效果最佳。
The LaBO_3:Eu,Gd powders were perpared by microwave induced combustion method using lanthanum(III) nitrate hydrate,europium oxide,gadolinium oxide,and boric acid as reaction raw materials,glycine as combustion agent,and natrium carbonicum calcinatum as cosolvent.The effects of the factors,such as Eu/Gd doping amount,microwave power,calcination temperature and time,on the product are discussed.The powders are characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),photoluminescence spectroscopy(PL) and ultraviolet-visible diffuse reflectance spectroscopy(UV-Vis DRS).The results show that Eu,Gd codoped LaBO_3 has the best effect when the doping amount of Eu is 2% and that of Gd is 3%,the calcination temperature is 500 ℃,and the calcination time is 3 h.
