Abstract

The film laser concept has attracted much attention from both fundamental and practical points of view. However, to obtain a very thin film encounters the difficulty in realizing ultrahigh doping level of rare earth ions in a very thin film. In this work, a series of transparent Er³⁺/Yb³⁺ co-doped Al₂O₃-SiO₂ / P₂O₅-SiO₂ glass thin films with rare earth ions doping level up to 20 mol% were fabricated by sol-gel spin-coating method. The roughness value of film surface was characterized with AFM technique. The luminescent spectra and the corresponding FWHM of Er³⁺/Yb³⁺ co-doped films are compared and some other spectroscopic properties are discussed.
