Abstract

We report on the synthesis and spectroscopic characterization of Sm3+-doped K2YF5 microparticles. The particles were synthesized via the hydrothermal technique, yielding a particle size of approximately 20 μm 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 Sm3+ in the Crm s point group symmetry centres of K2YF5 yields good approximation to the data.
