THE OPTICAL PROPERTIES OF GADOLINIUM DOPED CERIUM OXIDE THIN FILMS FORMED BY E-BEAM TECHNIQUE

The purpose of this work is to study optical properties of gadolinium doped cerium oxide thin films. GDC thin films have been deposited using e-beam technique on quartz substrates. Transmittance spectra of formed GDC thin films was measured using Ocean Optics spectrometer and were calculated optical parameters of GDC using Swanepoel method. The refractive index conversely depends on porosity of deposited GDC thin films. In addition refractive index have tendency to increase when increasing deposition rate. The bang gap of GDC thin films have not linearly tendency. It might depend on existence of Ce3+ ions, oxygen vacancies and various types of defects.
