Adelmo S. Souza,Luiz Antônio de Oliveira Nunes,Ivan G.N. Silva,Fernando Oliveira,Leonis Lourenço da Luz,Hermi Felinto de Brito,Maria C. F. C. Felinto,Rute A. S. Ferreira,Serverino A. Júnior,Luís D. Carlos,Oscar L. Malta +10 more
TL;DR: A novel and of paramount importance aspect is that the calibration factor can be calculated from the Eu(3+) emission spectrum avoiding the need for new calibration procedures whenever the thermometer operates in different media.

On the role of certain rotational invariants in crystal‐field theory
TL;DR: In this paper, the effect of the crystal field Hamiltonian in mixing free ion states is represented in second order by an effective operator acting only on the free ion state under consideration, and the shifts in the centers of gravity of the freeion levels caused by J mixing are derived in terms of three parameters s2, s4, s6.

Crystal field invariants and parameters for low‐symmetry sites
Yau Yuen Yeung,D.J. Newman +1 more
TL;DR: In this article, a new method of estimating crystal field parameters is proposed using crystal field invariants in conjunction with the superposition model, and the importance of using a fixed reference frame throughout a series of fitting based on approximate symmetries is stressed.
