Science and Engineering Optical absorption and fluorescence properties of Dy 3 + : SFB glasses

This paper presents the preparation and spectroscopic characterization of Dydoped sodium fluoroborate (SFB) glasses of the type (50-x) B2O3 + 25 Na2O + 10 CaF2 + 10 AlF3 + 5 LaF3 + x DyF3 (x = 0.01, 0.1, 0.5,1.0, 2.0 and 4.0 mol%). By measuring the area under absorption bands, the experimental oscillator strengths are determined. The Judd-Ofelt (J-O… CONTINUE READING
