Synthesis and Characterization of Triply Doped Nano-Composite Alumina-Phospho- Silicates SiO2-P2O5-Al2O3 with Er3+, Sm3+ and Yb3+ Ions Prepared by Sol Gel Technique in Two Different Forms Thin Film and Monolith
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.
