In this research, the authors give an analysis of surface structural morphology and optical waveguide properties of gadolinium oxide (Gd₂O₃) and gadolinium oxide europium doped (Gd₂O₃:Eu³⁺) films as prepared via the sol-gel and dip coating methods under atmospheric and clean room conditions. After describing sol-gel preparation routines, the authors further give observations of homogeneous surface morphological as characterized with scanning electron microscope (SEM) techniques. In addition, FTIR measurements of the Gd₂O₃ and Gd₂O₃:Eu³⁺ films and sol gels were made to monitor the decomposition and oxidation reactions that occur during processing. The samples' structural and resulting optical properties were studied and compared according to film thickness and surface morphological features.
