  ABSTRACT: Nano-composite monolith and thin film Alumina-Phospho-Silicates (SiO2-P2O5-Al2O3):Ln (Ln = Sm, Er, Yb) glasses activated by triply doped with three different rare earth ions (REIs) (Er3+:Yb3+:Sm3+) were prepared by modified sol-gel process. The composition of the prepared samples was as follow (SiO2:11P2O5:3Al2O3:1.2Er2O3:(1.2 - 3)Yb2O3:(0.7 - 1.3)Sm2O3). Tetra-ethyl-orthosilicate (TEOS), tri-ethyl-phosphate (TEP), erbium nitrate, ytterbium nitrate and samarium nitrate were used as precursor materials, respectively. The structure of the prepared samples was studied using X-ray diffraction (XRD), which revealed that the crystallite sizes of monolith and thin film samples both sintered at 900℃at constant Sm3+ concentration at 1.3 mol% (SPAE1.2Y1.8S1.3) have the following values 44 and 31 nm, respectively. Transmission Electron Microscopy (TEM) of the same prepared samples was used to confirm the presence of nano-structure phase. The photo-luminescence study will be evaluated for the prepared.
