Abstract
This paper reports on the development and optical analysis of Tb 3+-doped polyvinyl alcohol (PVA) films. A reference PVA film has also been prepared for which X-ray diffraction (XRD) spectral profile has been carried out; it was found that this polymer possesses a semi crystalline nature. Spectral analysis of the Tb3+:PVA polymer film has been made based on the measurement of the excitation, emission, and decay curves of the emission transitions (5D4 → 7F 6,5,4&3). Under a UV source (254 nm), a bright green emission was noticed from the surface of Tb3+:PVA film. The current study reveals that this terbium polymer film could be suggested as a novel green luminescent material.
