摘要：Sheet-like and rod-like nano Ca5(PO4)3(OH):0.05 Eu3+, xLi+(x = 0.01?0.07) phosphors were prepared by hydrothermal method. The structure, morphology and luminescent properties of samples were characterized by XRD, EDS, SEM, TEM and PL. The effects of morphology and Li+ doping on the luminescent properties of Ca5(PO4)3(OH):Eu3+ were studied. The results show that Li+ doping has little effect on the luminescent peak position and CIE color coordinate of sample, but it affects the crystallinity of sample and effectively improves its luminescence intensity. It was found that the luminescent properties of the samples were greatly affected by their morphology. The optimum Li+ doping amounts of nano sheet-like and rod-like Ca5(PO4)3(OH):0.05 Eu3+, xLi+ are 5 mol% and 3 mol% respectively. The luminescent intensity of the sheet-like sample was stronger than that of the rod-like sample. The luminescent lifetimes of nano rod-like sample is longer than that of the nano sheet-like sample. ? 2021 Elsevier GmbH
