Controllable hydrothermal synthesis of NaYbF4 and YbF3 with diverse morphologies and emission enhancement in β-NaYbF4: Er3+ upconversion micro-crystals via solvents codoping and Na+ dosage

Water-soluble Cit-NaYbF4:Tm3+with enhanced 802 nm emission by Sr2+ion doping forin vivofluorescence molecular tomography

“…In addition, based on the previous work of our research group, a preparation method with a high recurrence rate has been explored, but the process parameters need to be optimized. 50,51 In this paper, NaYb 0.98Àx F 4 :2%Tm 3+ /x%Sr 2+ upconversion nanoparticles (UCNPs) were successfully prepared by a onestep hydrothermal method and process parameter optimization strategy. The effect of ion doping on the size of UCNPs was systematically studied.…”
