This study concerns the synthesis as well as structural and morphological characterizations of pure and Ce-doped ZnO nanorods synthesized by hydrothermal process. The synthesized nanorods were characterized in terms of their morphological, structural, compositional, and vibrational properties. XRD results indicated the pure wurtzite structure with good crystalline quality of the samples. The use of NaOH as caustic base favors the agglomeration of the rods to form flower-like nanostructures. EDAX measurements show Zn rich materials. FTIR measurements confirm that the synthesized nanorods are high purity. The Raman spectroscopy studies showed that Ce ions shift the vibrational modes toward lower frequencies. The peak related to E₂ (high) mode in pure ZnO (NaOH) is relatively intense compared with that of pure ZnO (KOH) and the opposite result is observed in Ce-doped ZnO. After the introduction of Ce atoms, the Raman peaks shifted and asymmetrically broadened due to anharmonic effects originating from quantum-phonon-effect confinement.

本研究涉及通过水热法合成的纯Ce掺杂的ZnO纳米棒的合成以及结构和形态特征。合成的纳米棒的形态，结构，组成和振动特性均得到了表征。XRD结果表明样品具有纯净的纤锌矿结构和良好的结晶质量。NaOH作为苛性碱的使用有利于棒的团聚以形成花状的纳米结构。EDAX测量显示富含锌的材料。FTIR测量证实合成的纳米棒是高纯度的。拉曼光谱研究表明，铈离子使振动模式向低频移动。与E ₂相关的峰与纯ZnO（KOH）相比，纯ZnO（NaOH）中的（高）模式相对强烈，而Ce掺杂ZnO中观察到相反的结果。引入Ce原子后，由于源自量子声子效应限制的非谐效应，拉曼峰发生位移并不对称扩宽。
