| Abstract | ||
| Dysprosium ions Dy3+ Doped with silicon dioxide nano particular was prepared via sol–gel method. The spectroscopic properties of Dy3+:SiO2 sample was investigated by UV- Visible spectroscopy and fluorescence spectroscopy. The fluorescence spectrum for Dy:SiO2 sample is obtain by using excitation light source at wavelength 360nm, two peaks recorded at the wavelength around 482nm and 574nm . The spectroscopic properties of Dy:SiO2 show that the doped silica samples have a suitable peak emission cross-section σem in comparable with other results, thus it may suggests to use Sol – Gel to made of Dy : SiO 2 as solid state Laser active medium. | ||
