Optical properties of the SiO2-Na2O-CaO-nd2O3 glasses
Problem statement: This study researched on different physical and optical properties of Nd 3+ doped soda-lime-silicate glass. The glasses containing Nd 3+ in (65-x) SiO 2 : 25Na 2 O: 10CaO: xNd 2 O 3 (where x = 0.0-5.0 mol%) had been prepared by melt-quenching method. The density and molar volum...

| Summary: | Problem statement: This study researched on different physical and optical properties of Nd 3+ doped soda-lime-silicate glass. The glasses containing Nd 3+ in (65-x) SiO 2 : 25Na 2 O: 10CaO: xNd 2 O 3 (where x = 0.0-5.0 mol%) had been prepared by melt-quenching method. The density and molar volume increase with increasing of Nd 2 O 3 concentration due to increasing of Non Bridging Oxygens (NBOs) in glass matrix. Approach: The optical spectra were measured and evaluated their optical band gap and found to decrease with increasing of Nd 2 O 3 concentration. Results: Moreover, these results showed that the refractive index of glass does not only depend on the density but also depend on the electronic polarizability of the glass. Conclusion: The values of polarizability of oxide ions, theoretical optical basicity were also determined. © 2010Science Publications. |
