摘 要:Using a hydrothermal method,by adjusting the reactant ratios,the hydrothermal temperatures,the hydrothermal time,and the pH values of prepared solutions,1 mol.%Eu3+ doped K-Lu-F system optical materials were synthesized under control.For comparison,the sample was also synthesized by a co-precipitation method.The X-ray diffraction(XRD) results suggested that the final crystalline phases had great relations with the hydrothermal synthesis conditions.The field emission scanning electron microscopy(FE-SEM) images and the energy-dispersive spectroscopy(EDS) patterns indicated that the morphologies and the components of some representative samples also varied with the synthesis conditions.Eu3+,acting as a probe,exhibited different optical properties in the K-Lu-F system optical materials,which also indirectly proved the phase evolution of the final products.The results suggested that there were many crystalline phases with different symmetry in the K-Lu-F system.They would be good host matrices for the emitters.
