In this paper, we report the mild sonochemical synthesis of hexagonal (β) NaYF4:Yb,Er mesocrystals at
low temperature of 40 °C. The nucleation and transformation of crystal structures is investigated in
the course of time, and it is shown that the pure β phase is obtained after 2 h of pulsed sonication.
The crystallization of orthorhombic YF3:Yb,Er and cubic (α) NaYF4:Yb,Er precedes the appearance of a
thermodynamically stable β NaYF4:Yb,Er phase. Based on the evolution of the nanoparticle morphology,
it is concluded that the transition from a to β phase is consistent with the dissolution-recrystallization
process, while the final shape of mesocrystals is a consequence of the oriented attachment growth in
the newly formed b phase nanocrystallites along two planes. The structural properties of all compounds
are analyzed and correlated with their thermal and optical characteristics. The pump power dependence
of green and red emissions confirms that only two-photon process is inv...olved in up-conversion, which is
superior in β phase mesocrystals.
