Optical basicity
WebApr 28, 2024 · The optical basicity follows the same trend as the electronic polarizability, which can be attributed to the more acidic nature of P 2 O 3 compared with TiO 2. Moreover, the decrease of the optical basicity with increasing TiO 2 content supports the low ability of TiO 2 compared with P 2 O 5 to transfer electrons to the surrounding cations.
