1 Using the Judd-Ofelt theory to analyze the lattice structure of the Dy+3 ions doped lithium-sodium aluminoborate glass = Sử dụng lý thuyết Judd-Ofelt để phân tích phổ về cấu trúc mạng của thủy tinh lithium-sodium aluminoborate glass pha tạp ion Dy+3 / Tran Ngoc // .- 2021 .- Số 02(45) .- P. 109-116 .- 540

In this work, we prepared and studied spectroscopic properties of Dy3+ ions in lithiumsodium aluminoborate glasses. Judd - Ofelt theory has been used to evaluate intensity parameters Ωλ (λ = 2, 4, 6) by analyzing the absorption spectrum of ABLN: Dy3+ glass, and calculated the radiative transition probabilities, branching ratios, radiative lifetimes of 4F9/2 excited level, stimulated emission cross - section for selected.
