摘　　要：以 Ce(NO3) 3· 6H2 O为前驱物 ,加入火棉胶作为粘度调节剂 ,采用 sol-gel提拉法制备了均匀透明的 Ce O2 纳米薄膜 ,对其性能进行了研究 ,并用光声光谱确定了 Ce O2A novel sol gel dip coating process was adopted to prepare nanocrystalline ceria thin films with cerous nitrate as starting material and collodion as a viscosity increasing agent. The function of collodion was discussed. This novel dip coating process provided a good reproducibility of homogeneous ceria thin films. The spectral and crystal properties of ceria thin films were studied and the results indicated that the colour of ceria thin films mainly resulted from interference.
