Hydrothermal Synthesis and Luminescent Properties of BiPO₄:Eu³⁺ Phosphors

Abstract:

Eu³⁺ doped BiPO₄ red phosphor was prepared by hydrothermal method using C₂H₆O₂ as dispersant. The structure and composition of the samples were characterized by IR and XRD. The results showed that with the increase of hydrothermal temperature and hydrothermal time, the crystal structure of BiPO₄ changed from hexagonal phase to monoclinic phase. The luminescence properties of Eu³⁺ doped BiPO₄ were characterized by excitation spectra and emission spectra. The results showed that both monoclinic phase phosphor and hexagonal phase phosphor can be light emitting. Different crystal structures of Eu³⁺ doped BiPO₄ samples had the same emission peaks in emission spectra excited by blue light wavelength of 395 nm, which corresponded to the ⁵D₀→⁷F₁ transition at 590nm and ⁵D₀→⁷F₂ transition at 614nm of Eu³⁺. The luminescence intensity of monoclinic phase Eu³⁺ doped BiPO₄ was significantly stronger than the hexagonal phase sample’s luminescence intensity.
