摘要：CaB4O7:Eu3+ phosphor was firstly prepared by two-step hydrothermal method using Ca2B10O17 center dot 5H(2)O:Eu3+ as the precursor. The structure, morphology and luminescent properties of CaB4O7:Eu3+ and Ca2B10O17 center dot 5H(2)O:Eu3+ were characterized by XRD, FTIR, EDS, SEM, TG-DTA and PL. Moreover, the possible reaction and formation mechanism of Ca2B10O17 center dot 5H(2)O:Eu3+ and CaB4O7:Eu3+ were proposed. The results show that the optimal emission and excitation peaks of the precursor and the product are different, and the emission intensity of CaB4O7:Eu3+ is much stronger than that of Ca2B10O17 center dot 5H(2)O:Eu3+. It was also found that the CaB4O7:Eu3+ prepared by two-step hydrothermal method exhibits stronger emission intensity and better red color purity than that prepared by conventional solid-state reaction method.
