Abstract

We report on the synthesis and spectroscopic characterization of Sm $^{3 +}$ -doped K $_{2}$ YF $_{5}$ microparticles. The particles were synthesized via the hydrothermal technique, yielding a particle size of approximately 20 $μ$ m in length. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses confirmed their orthorhombic crystal structure. A combination of absorption and laser excited fluorescence performed on samples cooled to 10~K, allow for the determination of {56} experimental crystal-field levels. A parametrised crystal-field analysis for Sm $^{3 +}$ in the C $_{s}$ point group symmetry centres of K $_{2}$ YF $_{5}$ yields good approximation to the data.
