Abstract
Nano-composite monolith and thin film Alumina-Phospho-Silicates (SiO 2 -P 2 O 5 -Al 2 O 3 ):Ln (Ln = Sm, Er, Yb) glasses activated by triply doped with three different rare earth ions (REIs) (Er 3+ :Yb 3+ :Sm 3+ ) were prepared by modified sol-gel process. The composition of the prepared samples was as follow (SiO 2 :11P 2 O 5 :3Al 2 O 3 :1.2Er 2 O 3 :(1.2 - 3)Yb 2 O 3 :(0.7 - 1.3)Sm 2 O 3 ). 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 Sm 3+ concentration at 1.3 mol% (SPAE 1.2 Y 1.8 S 1.3 ) 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.
