This work specifies the synthesis and the characterization of amorphous and crystalline powder and thin films materials belonging to the Er2O3-Y2O3-Al2O3-B2O3 system. The main objective of this work was to develop an amorphous thin film samples near to the YAl3(BO3)4 composition with yttrium partially substituted by erbium (Y1-xErxAl3(BO3)4), with the aim to applied these thin films as waveguide amplifiers in the integrated optical systems. The polymeric precursor and the sol-gel methods were applied in order to produce such thin films. To well define the best conditions to obtain amorphous and dense thin films, the powder samples of the same compositions were first characterized by thermal analysis techniques, X-ray diffraction, IR and Ram...
