Abstract

Abstract: The praseodymium orthoborates λ-PrBO₃ and ν-PrBO3 were synthesized from Pr₆O₁₁ and H₃BO₃ by solid state reaction method at 1200 and 1500℃, respectively. The crystal structure of ν-PrBO₃was refined on the basis of single-crystal X-ray diffraction data. It crystallizes in the triclinic system belonging to space group Pwith lattice parameters: a = 0.6302 (4) nm, b = 0.6521 (4) nm and c = 0.6525 (4) nm, and α = 94.312(7)°, β = 107.335(7)°, γ = 106.455(7)°, V = 0.2417(2) nm³, Z = 4. The phase transition process from λ-PrBO₃ to ν-PrBO₃ was also investigated. The optical band gaps of λ-PrBO₃ and ν-PrBO₃ are both determined to be about 4.96 eV according to the diffuse reflection spectra. There is no emission of Pr3+ in the visible range for both of λ-PrBO3 and ν-PrBO₃under X-ray and UV excitation.

Key words: ν-PrBO₃ crystal structure, phase transition, optical properties
