Abstract EN
Partially phosphorylated polyvinyl alcohol (PPVA) films were prepared at five mole ratios of phosphoric acid (PA) using solution casting technique.
The optical properties of the PPVA films were examined using UV-visible (UV) and photoluminescence (PL) spectroscopy.
The UV absorption spectra reveal that the absorption peaks are blue-shifted with an increase in PA concentration added to the pure PVA.
The PL spectra show the presence of peaks which are characteristic of isotactic (389–398, 460–462 nm), syndiotactic (418–420 nm), and atactic (440–446 nm) configurations of the PPVA.
The results also show the peak of O–P–O bonding at a wavelength range of 481–489 nm.
