摘要:本文着重研究了常压下采用液相法合成均分散Cu2O空心球和实心球.
此项工作中,我们用自制Cu(OH)2来制备目标产物,采用还原剂抗坏血酸,成功地制得了纯相的氧化亚铜.初步探索了反应温度、反应时间、反应物配比、反应物浓度和搅拌速度对Cu2O纳米粒子尺寸的影响.采用X-射线转靶衍射仪(XRD)、透射电子显微镜(TEM)和扫描电子显微镜(SEM)、紫外-可见光吸收和荧光发射光谱(PL)对其结构、形貌及光学性质进行了表征和研究.
研究发现,反应物配比是目标产物尺寸的主要控制因素,而搅拌速度的变化会对产物的结晶会产生一定的影响.我们发现所合成产物的紫外-可见光吸收峰和荧光发光峰的位置较Cu2O块体材料发生了蓝移.
关键词:液相法;氧化亚铜;空心球;蓝移

In a work,we use self-made Cu (OH) 2 to prepare the goal product,uses the reducing agent antiscorbutic acid,successfully system pure cuprous oxide.Initially has explored the reaction temperature,the reaction time,the reactant allocated proportion,the reactant density and the mixing speed to the Cu2O nanometer granule size influence.Used the X- beam to transfer the target diffraction meter (XRD),the transmission electron microscope (TEM) and the scanning electron microscope (SEM),the purple visible light absorption and the fluorescence emission spectrum (PL) to its structure,the appearance and the optical quality has carried on the attribute and the research research discovery,the reactant allocated proportion is the goal product size primary control factor,but the mixing speed change could be able to have the certain influence to the product crystal.We discovered the synthetic product purple visible light absorption peak and the fluorescence sent the photopeak the position to compare the Cu2O block body material to occur blue moved
