Summary The year 2012 marked the golden anniversary of the Judd-Ofelt (J-O) theory as a tool used widely for the theoretical description of the spectroscopic properties of the lanthanide materials; in fact it is the only tool, as pointed out in the title of this chapter, that is used in...

The Judd–Ofelt theory can describe the spectral intensities of Nd3+ transitions in the oxyfluoride glass ceramics containing CaF2 nanocrystals quite well. The intensity parameter Ω2 is in the range of 3.5–3.6×10−20 cm2 for the precursor glasses, while it decreases to 2.4–2.9×10−20 ...
