1. Efeitos fotoinduzidos em vidros e filmes de fosfato de antimônio dopado com chumbo e fosfato de antimônio dopado com cromo / Photoinduced effects in glasses and films of lead doped antimony phosphate and chromium doped antimony phosphate
The present work is about the study of the optical and structure properties of doped antimony phosphate glasses and thin films. The glasses were produced by the melting of precursors [Sb(PO3)3]n + Sb2O3 using PbO and Cr2O3 as dopant at 900 °C in vitreous carbon crucibles, then poured and quickly cooled into steel molds. The vitreous composition are: 20% [Sb

2. Preparação e caracterização do Sistema polifosfato misto contendo o ion Erbio
According to available published data, antimony polyphosphates have not attracted much attention from researchers. Currently polyphosphates of trivalent elements, including those of lanthanides, are widely employed in glasses suitable for light transmission within the region of telecommunication windows. In this case, the combination of antimony and rare ear
