Crystal field study of ytterbium doped Lu₂SiO₅and Y₂SiO₅under a magnetic field

Abstract

Yb 3+ crystal field excitations in ytterbium doped Y 2 SiO 5 and Lu 2 SiO 5 single crystals and thin films are studied under an applied magnetic field. The ground and excited state g-factors that are needed for the calculation of reliable crystal field Hamiltonian parameters are determined. Some of the Yb 3+ ions that substitute for the Y 3+ or Lu 3+ ions give rise to Yb 3+ -Yb 3+ magnetically interacting pairs as confirmed by their crystal field absorption bands under a magnetic field. The overall crystal field excitation characteristics confirm the strong similarities between the single crystals studied and thin films.

“…S2 and S3). The values for B b are in agreement with those reported in [31]. In a first step, the ground state g tensor measured by EPR was compared to the experimental data to check for sample misalignment.…”

“…31,42 Due to the two crystallographic sites, which generally divide in two sub-sites under a magnetic field, and the two Yb 3+ isotopes with I = 0, many lines were observed for magnetic fields B in the range 50-1000 mT. Fig.…”

Reduction of Photoluminescence Quenching by Deuteration of Ytterbium-Doped Amorphous Carbon-Based Photonic Materials

“…Incorporation of Yb into ceramic-based (YAG [11,12,13], Y 2 SiO 5 (YSO) [14,15,16], KY(WO 4 ) 2 [17], NaLu(WO 4 ) 2 [18], and Al 2 O 3 [19,20]) wide bandgap semiconductors, oxide-based semiconductors (ZnO [21,22,23], TiO 2 [24,25], In 2 O 3 [26]), III–V group based materials (AlN [27]), and Si-based [28] thin film hosts using various deposition techniques, have been shown to produce luminescence at a wavelength of around 1 μm. For Yb doped YAG [11], YSO [14,15], and KY(WO 4 ) 2 [17] thin films, the liquid phase epitaxial (LPE) method has been employed to fabricate homogeneous crystalline films from a molten solute diluted in a solvent.…”

“…In addition, rare‐earth elements (Ce 3+ , Yb 3+ , Tm 3+ , etc.) activated Y 2 SiO 5 and Y 2 Si 2 O 7 are also reported as candidates to replace Nd 3+ :YAG (Y 3 Al 5 O 12 ) solid lasers …”
