文摘

Optical properties of three fluoride single crystals (YF₃, LiLuF₄ and KY₃F₁₀) doped with Nd³⁺ ions have been studied. Low temperature absorption spectra lead to the Stark energy level scheme up to 29 000 cm⁻¹. From room temperature absorption measurements and using the Judd–Ofelt theory, the Ω₂, Ω₄ and Ω₆ parameters have been obtained in the LiLuF₄:Nd³⁺ and KY₃F₁₀:Nd³⁺ crystals and radiative lifetimes have been calculated.
