Title: Intense 1.6 μm fluorescence of Nd{sup 3+} doped cadmium bismuth silicate glasses

In this work, Judd-Ofelt analysis is applied to rare-earth (RE = Nd{sup 3+}) doped cadmium bismuth silicate (20CdO⋅xSiO{sub 2}⋅(79.5−x)Bi{sub 2}O{sub 3}⋅0.5Nd{sub 2}O{sub 3} (CSBN)) glasses in order to evaluate their potential as well as both glass laser systems and optical materials. The phenomenological Judd-Ofelt parameters (Ω{sub 2}, Ω{sub 4}, Ω{sub 6}) are determined for RE ions with their quality factors and compared with the equivalent parameters for several other hosts. The calculated value of stimulated emission cross-section for {sup 4}F{sub 3/2}→{sup 4}I{sub 11/2} has high and varies 14.72×10{sup −20} to 9.66×10{sup −20} cm{sup 2} with Bi{sub 2}O{sub 3} content in the host glass. The results point out that the glass system is good candidate for the development of photonics devices which are operating near infrared spectral range. Further, the FTIR results reveal that the glasses have BiO{sub 6}, SiO{sub 4} and non-bridging oxygen as local structure.
