Optically active films in the Y2Ti2O7–Er2Ti2O7 (YETO) system have been deposited using the aerosol–gel process. Photoluminescence properties closely depend on the film crystallization degree. Dilution of erbium ions within a crystalline Y2Ti2O7 m

Optically active Er2Ti2O7 (ETO) and Y2-xErxTi2O7 (YETO) films have been successfully deposited using the aerosol-gel process. Several heat-treatment procedures are investigated in the 600–850 °C range. ETO and YETO films start to crystallise in th

Optically active thin films in the system Y2Ti2O7-Er2Ti2O7 (YETO) have been deposited using the Aerosol-gel process. Depending on the heat-treatment temperature, amorphous or crystalline films could be prepared in the range 600–950°C. The study sh

Nd-doped silica glasses have been prepared from a base catalyzed sol-gel solution. The photoluminescence (PL) spectrum and lifetime of the glasses have been studied with respect to their microstructure and chemical composition. It is shown that the g

Channel waveguides, when doped with rare-earth ions, are attractive for integrated optics devices (amplifier, micro-lasers). This paper describes rare-earth doped lead-based fluoride glass channel waveguides produced via mechanical profiling, photoli

Two types of liquid-source CVD processes are proposed for the growth of rare earth-doped alumina thin films suitable as amplifying media for integrated optic applications. Amorphous, transparent, pure and erbium- or neodymium-doped alumina films were
