摘要

An Er³⁺:BaGd₂(MoO₄)₄ single crystal has been grown by the Czochralski method. The polarized absorption spectra, polarized fluorescence spectra, and fluorescence decay curves were measured. In the framework of Judd-Ofelt theory, intensity parameters, spontaneous emission probabilities, fluorescence branching ratios, and radiative lifetimes were calculated. Besides, green upconversion fluorescence was also observed.
