Bulk Crystal Growth and Spectroscopic Properties of Dy3+/RE3+(RE=Tb,Eu)Co-doped Ca3Li0.275Nb1.775Ga2.95O12(CLNGG)Laser Crystals
摘要
Abstract
In this work,five kinds of crystals were successfully synthesized using the Czochralski method for the first time,namely Dy∶Ca3Li0.275Nb1.775Ga2.95O12(CLNGG),Dy,Tb∶CLNGG,Dy,Eu∶CLNGG,Tb∶CLNGG,and Eu∶CLNGG.A detailed investigation of spectral features and energy transfer mechanisms in such crystals was conducted by analyzing their optical absorption spectra,excitation and emission spectra,and fluorescence decay curves at ambient tem-perature.Calculations based on the Judd-Ofelt theory further elucidated these features.The results demonstrate that in the Dy3+system,co-doping with Tb3+and Eu3+ions not only enhances the emission cross-sections in the yellow wavelength re-gion but also improves the fluorescence quantum efficiency.These improvements are particularly beneficial for achieving efficient yellow light output from Dy3+.Additionally,the studies confirm the occurrence of reciprocal energy transfer be-tween Dy³⁺ and Tb³⁺ ions in Dy,Tb∶CLNGG crystals,whereas unidirectional energy transfer from Dy³⁺ to Eu³⁺ occurs in Dy,Eu∶CLNGG crystals.Based on the obtained research results,Dy,Tb∶CLNGG and Dy,Eu∶CLNGG crystals could be utilized as compelling and potential laser media for diode-pumped all-solid-state yellow lasers.关键词
