Abstract
We report on the synthesis, spectroscopy and energy transfer mechanisms of KY3F10 nanocrystals doped with trivalent samarium ions. Dopant concentration-dependent, measured fluorescence transients indicate energy transfer mechanisms that are dipole-quadrupole in nature. The inferred energy transfer rate is also considerably faster than what is reported in comparable hosts. We also observe the formation of α-KYF4:Sm3+ at high dopant concentrations, indicating a potential dopant limit for larger lanthanide ions. Unlike the bulk crystal, no divalent samarium is detectable in the nanocrystals.
