Rietveld Refinement: The experimental powder X-ray diffraction pattern of sample 1DA was refined using the Rietveld method by means of GSAS software. A Pseudo-Voight function was used to simulate the peak shape and the log-interpolate function with ten coefficients was used to simulate the background. The Rietveld refinement graphic is depicted in Figure S1, while the refined parameters (including the percentage of phase fraction) are included in Table S1 and Table S2.S2. Structural Characterization: Figure S2 shows the FT-IR spectra of samples 1D (δ), 1DA (δ + α), and 1A (α) as an example of the different crystal phases. The broad, weak bands at ≈ 3100–3500 cm–1 and ≈ 1640 cm–1 are assigned to the O–H stretching vibrations and H–O–H bending mode of H2O molecules, respectively. This indicates the presence of some absorbed water in the materials. In sample 1D, a notable difference is appreciated in the stretching and bending vibrational modes of H2O molecules, since they are associated with crystalline water molecules localized in the channels of the δ-KY3F10·xH2O host lattice. These bands are sharper and stronger. For all the samples, the Y–F host lattice vibrations were observed below 600 cm–1 . On the other hand, the FT-IR spectrum of sample 1DA can be interpreted as a combination of the spectra of samples 1D and 1A, which is very good agreement with the results of XRD and the coexistence of δ and α crystal phases in the same sample. It is observed a major response from the response of the α-phase (see indeed the Y–F host lattice vibrations), a fact that suggests that there is a higher amount of this crystal phase.S3. DLS measurements: Figure S3 shows the particle size distribution of samples doped with 1 mol% Eu 3+ content. For the DLS measurements, the powder concentration was 1 mg/mL in distilled water. Sample 1DA (α + δ) was previously filtered using a 0.4 µm cellulose filter to eliminate the agglomerates corresponding to the α-phase. Otherwise, neither a good dispersion nor good data from the DLS measurements could be obtained. The maximum peak for sample 1DA-filtered was found at 195 nm (mainly due to the δ-phase nanospheres), which is quite close to the value obtained for sample 1D (δ-phase), 175 nm. The obtained hydrodynamic diameters were in very good agreement with the SEM results.Peer reviewedElsevierConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202320232023info:eu-repo/semantics/datasethttp://purl.org/coar/resource_type/c_ddb1Publisher's versioninfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://hdl.handle.net/10261/333914reponame:DIGITAL.CSIC.
