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 factors for the
characteristics of the final products: morphology, size and crystallinity. As a result,
noticeable changes in their photoluminescence spectra and lifetimes were observed.
Quantum cutting processes or similar energy transfers between Eu3+ ions allowed
obtaining high quantum efficiencies, while the analysis of the 𝛺�����2 Judd-Ofelt parameter
suggested that the crystal field of Eu3+ was very similar in all the compositions. A welldesigned synthesis of Ln3+-doped fluorides can provide a full range of opportunities to
explore new phenomena. Thus, this study highlights the complexity of the fluoridebased systems, which are exceptional candidates for doping with luminescent
lanthanide ions and have very important characteristics for their future application in
bioanalytics, biomedics or photonics. Indeed, the color-tunable emissions of the
phosphors, which vary from orangish to yellow, could be interesting for their
application in white light-emitting diodes through their combination with blue chips. [-]
