Synthesis, structural, band gap, and optical properties of Ba3(PO4)2 hierarchical structural materials

A novel phosphate with CoII square planar coordination, BaCo0.5Fe(PO4)2: structural and magnetic features

“…5b) and the direct band gap energy is estimated from the intercept of the linear fit (dashed red line) with the energy axis. The obtained value of 2.83 eV is lower than the reported band gap in Ba 3 (PO 4 ) 2 41 ( E g = 4.89 eV) and likewise in α-Zn 3 (PO 4 ) 2 ·4H 2 O 42 ( E g = 3.6 eV). It is worth mentioning that phosphates with such a lower band gap might be used as a photocatalyst for reactions under UV-light or sunlight.…”

Ba3(PO4)2 Photocatalyst for Efficient Photocatalytic Application

“…Then, Zhang et al [ 34 ] investigated the hydrothermal synthesis of magnetic Fe 3 O 4 @Ba 3 (PO 4 ) 2 nanoflakes loaded by Ag‐nanoparticles as well as their antimicrobial activity toward water disinfection via adsorption/degrading microorganisms such as E. coli . Recently, Obulapathi et al [ 35 ] investigated the structural and optical properties of Ba 3 (PO 4 ) 2 nanomaterials. The results showed that pH value in the wet chemical synthesis method has a critical effect on the final product's crystal structure, which may change from rhombohedral to orthorhombic, as well as its morphology.…”
