稀土离子的多格位占据及能量传递
Multi-site Occupations and Energy Transfers of Rare-earth Ions
摘要
Abstract
The multi-site occupations and the energy transfers are ubiquitous in various fields of rare-earth ions activated luminescence materials and have important scientific and practical significance.The Ce3+ 4f-5d and the Eu3+ 4f-4f transitions represent two typical electronic transition types of rare-earth ions.We take Ce3+/Eu3+-activated E(δ)-Gd2Si2O7(Pnma),G-La2Si2O7(P21/n),and F-Eu2Si2O7(P(1))as the representative cases to discuss and revisit the multi-site occupations and the non-radiative energy transfers,focusing on the crystal structure,the phase purity of samples,the doping concentration,the spectral characterization,the energy transfer between lattice sites,and the spectral resolution.In the studies of luminescence materials activated by rare-earth ions,we must not only consider the self-consistency of the materials'crystal structures and their spectra,but also analyze the energy transfers(in-cluding the outgoing energy and the receiving energy)between lattice sites from the spectra and the luminescence de-cay dynamics.We hope that these contributions could inspire experiments and characterization for readers who are new to the related fields.关键词
