Elaboration and Characterization of Y_2O_3 Waveguide Thin Films Prepared by Sol-Gel Process

Waveguide thin films of yttrium oxide (Y 2O 3) were prepared by sol gel process.The films were successfully synthesized using yttrium acetate in methoxyethanol. A homogeneous and stable solution was obtatined by the reaction with diethylenertiamine. Precursor films were deposited using a dip coating method. Differential thermal analysis and infrared spectroscopy were used to characterize the Y 2O 3 egl and powder. XRD, scan electron microscopy, m line spectroscopy and waveguide fluorescence spectroscopy were used to characterize the films. The preliminary results show that this thin film is a good host material for active dopants and of great potential for future application in optoelectronics.
