“…Electron Paramagnetic Resonance (EPR) (12,13), susceptibility, 7 Li Nuclear Magnetic Resonance (NMR) (14) and optical spectroscopy (15) show planar XY anisotropy, but significant variation in the reported anisotropy ratio and the lack of a globally consistent set of crystal field parameters, prevented predictions of low-temperature properties. Susceptibility (16) and specific heat (17) show a transition around 380mK.…”

“…The UC luminescence mechanism for Yb 3+ /Er 3+ systems have been extensively investigated in various host materials [11,[13][14][15][21][22][23][24][25][26][27][28][29], including oxyfluoride glass ceramics [5][6][7]18,19] and therefore we do not address it in detail here. Under 980 nm laser light pumping the green emitting levels ( 2 H 11/2 , 4 S 3/2 ) are populated by the Yb 3+ -Er 3+ ET1 [ 2 F 5/2 (Yb 3+ ) + 4 I 15/2 (Er 3+ ) → 2 F 7/2 (Yb 3+ ) + 4 I 11/2 (Er 3+ )] and ET2 [ 2 F 5/2 (Yb 3+ ) + 4 I 11/2 (Er 3+ ) → 2 F 7/2 (Yb 3+ ) + 4 F 7/2 (Er 3+ )] processes (see Fig.…”

“…In addition, surface defects with relative large vibration energies like Si-O bonds (of about 1000 cm − 1 ) and hydroxyl ions (OH −1 ) (about 3500 cm −1 ) can bridge easily the non-radiative relaxation of 4 I 11/2 to 4 I 13/2 (only approximately 3600 cm −1 energy gap) [22] and therefore multiphonon relaxation rate is rather large (see below). The processes is followed by a subsequent energy transfer from Yb 3+ ion that will excite the Er 3+ ion to the 4 F 9/2 state accounting for an enhancement of the UC red emission [31] as it was in our study (Fig.…”
