This paper describes the preparation of new oxide host materials for Er 3+ based on GeO 2 by the sol‐gel method. The characterization of these new materials is reported, with particular regard to the crystallization behavior: the tendency of GeO 2 gels to crystallize during thermal treatment, in fact, is a critical problem. The investigated systems, powders and films, are GeO 2 ‐SiO 2 , with different compositions, and 80GeO 2 20M x O y , with M = Nb, Sn, Ti, Te.
