Analyses of the thermal shifts of spectral lines in Nd3+-doped LiYF4 laser crystal

The role of terminal ligands in the slow relaxation of magnetisation and luminescence thermometry of dinuclear NdIII complexes

“…3c). Moreover, as the temperature increases, the emission bands arising from the different M J sublevels overlap due to band broadening resulting from enhanced electron-phonon coupling, 53 and for {2-Nd 2 }, the component at 1055 nm also red-shifts towards 1060 nm for the same reason. 54 The ΔE between the two M J sublevels of the 4 F 3/2 level (Fig.…”

Research on the thermal shifts and electron–phonon coupling parameters of Ri lines for Cr3+ ions in LaGaO3 and LaAlO3 crystals

“…(1) which can explain only the red-shift of spectral lines [22,23], Eq. (2) can explain (or fit) consistently the red-shift, almost no-shift and blue-shift for the spectral lines of d n and 4f n ions in crystals [21,[24][25][26][27][28] because it contains the competition between the vibrational and static contributions to the thermal shifts. So, Eq.…”
