Laser site-selective spectroscopy of Nd3+-doped Y2SiO5

Zeeman spectroscopy and crystal-field analysis of low symmetry centres in Nd3+ doped Y2SiO5

“…In this work, we report on Zeeman absorption spectroscopy and parameterised crystal-field modelling of both Nd 3+ centres in Y 2 SiO 5 through the use of experimentally inferred crystal-field energy levels and Zeeman directional electronic g values as well as utilising the electron paramagnetic resonance (EPR) measured ground-state g tensor. Experimental electronic levels determined from laser site-selective spectroscopy were reported in [24] whilst the EPR measurements are from the literature [15,25]. We demonstrate very good agreement between the calculated and experimental crystal-field energy levels and directional Zeeman g values.…”

“…These follow the convention utilised in the standard 'Dieke diagram' to label the Stark levels of the crystal field splitting of the Nd 3+ manifolds. The experimental crystal field energy levels used in the current analysis were collected through laser site-selective and temperature-dependent absorption spectroscopy [24]; these energy levels are given in tables 1 and 2.…”

Theoretical Determination of the Electronic Structures and Energy-Level Splitting for Pr3+-Doped Y2SiO5 Crystals

“…The electronic properties and crystal field parameters (CFPs) of the two doping structures were also studied. Alizadeh et al reported the Nd 3+ -doped Y 2 SiO 5 crystal, and two doping sites of Nd 3+ in Y 2 SiO 5 were found. They also observed the crystal field levels of two different doping structures.…”

“…More importantly, Equall et al studied the influences of different doping sites of Pr 3+ in Y 2 SiO 5 and concluded that fluorescence spectra are closely related to the crystal structures . According to the literature studies, , there are two different sites for the Pr 3+ doped into the host Y 2 SiO 5 . The two distinct structures could result in completely different energy-transfer processes.…”

“…More importantly, Equall et al studied the influences of different doping sites of Pr 3+ in Y 2 SiO 5 and concluded that fluorescence spectra are closely related to the crystal structures. 22 According to the literature studies, 23,24 25−31 the energy levels of Y 2 SiO 5 :Pr are systematically studied with a new set of CFPs. Finally, several electric dipole (ED) and magnetic dipole (MD) transitions are deciphered.…”
