摘要：Novel Ca2B2O5H2O:Eu3+ nanotubes, constructed with nanobelts, were prepared using a hydrothermal method. The Ca-3(BO3)(2):Eu3+ nanobelts with a thickness of about 100nm were made for the first time using a two-step hydrothermal process with Ca2B2O5H2O:Eu3+ as the precursor. The samples were characterized by energy dispersive X-ray spectroscopy, X-ray diffraction, Fourier transform infra-red spectroscopy, thermogravimetry differential thermal analysis and scanning electron microscopy. The relationship between Ca-3(BO3)(2):Eu3+ and Ca2B2O5H2O:Eu3+ was also studied. Possible reaction and growth mechanisms for Ca2B2O5H2O:Eu3+ and Ca-3(BO3)(2):Eu3+ were proposed. Ca-3(BO3)(2):Eu3+ preserved the basic microstructure unit of Ca2B2O5H2O:Eu3+. Both Ca2B2O5H2O:Eu3+ and Ca-3(BO3)(2):Eu3+ exhibited red emissions centred at 614nm, but the maximum excitation peaks for Ca2B2O5H2O:Eu3+ and Ca-3(BO3)(2):Eu3+ differed. Ca-3(BO3)(2):Eu3+ exhibited higher photoluminescence intensity but a lower R/O value than Ca2B2O5H2O:Eu3+.
