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 literature since it was

Environment-friendly pigments based on AFeO3 (A = La, Pr, Nd, Sm, Gd, Tb, Y or Yb) with high near-infrared (NIR) reflectance were synthesised by a coprecipitation method at 1200 °C. The Rietveld refinement analysis showed single-phase orthorhombic p

In this study Eu3+-doped yttrium fluorides were designed by ultrasound-assisted processes at different pH values (4.0–9.0). This novel strategy has enabled to obtain materials with intriguing morphologies and modulated crystal structures: α-KY3F10

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 response of the dopant is repor
