Up-converting nanoparticles (UCNPs) have unique optical properties to convert NIR to VIS light, and therefore are widely used in optoelectronics, forensic, medicine, etc. [1,2]. During the last decade interest in obtaining of the pure hexagonal (β) NaYF4:Yb/Er phase through some environmental friendly method which could be easily scaled-up is permanently present in scientific community. Different synthesis methods, like co-precipitation, thermal decomposition, hydro- and solvo-thermal methods were usually reported like promising ones, but obtaining of the highly efficient (β) phase is usually coupled with harsh processing conditions [3]. This phase is characterized by a higher degree of crystal asymmetry and multisite dopant accommodation which ensures better luminescence response than of cubic (beta) phase. To prevent nucleation of kinetically stable alpha phase, we applied for the first time ultrasound treatment (20 kHz, Vibra Cell VCX750 Sonic) to the simple mixture of the rare eart...h nitrates and NaF in different solvents (ethanol and water) for 30, 60, 90 and 120 min.
