In this article we present possibility of obtaining nano-phase structures in glasses and optical fibers doped with RE ions. Effect of phosphate on structural and optical properties of antimony-germanate glasses doped with Eu3+ions have been investigated. Modification of Sb2O3 - GeO2 - SiO2 - Al2O3 - Na2O glass system by P2O5 (up to 10 mol.%) shows possibility of creation of the EuPO4 phosphate nanophase...
A group of nanocrystalline polyphosphates is presented showing the advantages arising from their spectroscopic properties. Their unique optical features are related, among others, with their structural properties. For example, reduced cross relaxation processes between doped lanthanide ions are observed in tetraphosphate matrices due to the relatively large active ions distance. For selected praseodymium...
