[[2][3]]The theory was introduced independently in 1962 by Brian R. Judd of the University of California, Berkeley, and PhD candidate George S. Ofelt at Johns Hopkins University.[2] Their work was published in Physical Review and the Journal of Chemical Physics, respectively.
[1][2]Judd and Ofelt did not meet, however, until 2003 at a workshop in Lądek-Zdrój, Poland.
Judd and Ofelt's work was cited approximately 2000 times between 1962 and 2004.[ Brian M. Walsh of NASA Langley places Judd and Ofelt's theory at the "forefront" of a 1960s revolution in spectroscopic research on rare-earth ions.[2]]
Theory
{{expand section|date=November 2015}}Application software
Judd-Ofelt intensity parameters from absorption spectrum of any Lanthanide can be calculated by the RELIC application software.[3]
Judd-Ofelt intensity parameters and derived quantities (oscillator strengths, radiative transition probabilities, luminescence branching ratios, excited state radiative lifetimes, and estimates of quantum efficiencies) from the emission spectrum of Eu3+ doped compounds, can be obtained by the JOES application software.[11]
