Predict optical properties of Dy3+ ions doped double potassium gadolinium fluoride crystal from absorption spectra
Main Article Content
Abstract
Abstract. Double potassium gadolinium fluoride crystal doped with 5.0 mol % of Dy3+ ions (K2GdF5:Dy3+) was synthesized under hydrothermal condition. The absorption, luminescence spectra and lifetime of K2GdF5:Dy3+ sample were measured at room temperature. Judd – Ofelt (JO) theory is used to study the spectral properties and to calculate the radiative transition probabilities. The prediced branching ratios (βR), radiative lifetime (ιR), integrated emission cross – section (Σif) and stimulated emission cross – sections (σ(λp)) of the 4F9/2 excited level are reported.[u1]
Keywords: K2GdF5 single crystal, J-O theory.
