A site-selective fluorescence spectroscopy study of the crystal phases of KY3F10: Leveraging the optical response of Eu3+ ions
Elsevier (2023-04-18)The present work deals with the investigation of the site-selective symmetries in Eu3+-doped KY3F10 with different crystal phases. Employing time-resolved fluorescence line-narrowing (TRFLN), a study of the luminescent ... -
Luminescence and structural properties of Ca1-xZrO3:Eux: An experimental and theoretical approach
Sao Paulo State University. Institute of Chemistry (2022-04-11)The influence of Eu3+ cations in the host matrix of CaZrO3 was investigated by analyzing its luminescence and structural properties. The Ca1-xZrO3:Eux crystals (x = 0.01, 0.02, 0.04, and 0.08 mol%) were obtained by a simple ... -
The unexplored δ-phase of KY3F10: toward novel Eu3+-doped nanoplates with a ‘super-diamond’ structure for optical applications
Elsevier (2021-12-07)This article describes a new, simple, and high-yield method based on a sonochemical process for obtaining the δ-KY3F10·xH2O compound with a ‘super-diamond’ structure, a material that has been completely neglected in the ... -
Tuning the optical and photoluminescence properties of high efficient Eu3+ -doped KY3F10 phosphors by different synthetic approaches
Elsevier (2021)Eu3+-doped KY3F10 materials with a dopant content between 0 and 5 mol% were prepared based on the nominal composition K(Y3-xEux)F10 using different synthetic routes. The reaction conditions have been proven to be critical ... -
Unraveling the superior role of dicarboxylic acids as surface chelators in Eu3+-doped yttrium fluorides: A systematic modulation of the crystal phases and morphologies for highly tuned optical performance
Elsevier (2021-06-16)Eu3+-doped YF3 and KY3F10 phosphors have been prepared hydrothermally in a wide range of pH values without the use of surface chelators and adding oxalic or tartaric acid. We have proved, for the first time, the usefulness ...
